I didn’t watch the whole video but you did make me realize that in order to solve the question I needed to look at the WHOLE triangle, and not just the two parts. THANK YOU
salute to this man, his videos are giving me so much confidence to take the exam without worrying how hard math is, I used to love math but in some extent it's not. maybe because of the way how teachers taught it to me, but now I think I'm starting to love math again. thank yoy
Oh thank you so much!! Your voice is so calming and you don't go too fast. It's wonderful and thanks again for making videos to help all of us. Trigonometry is really quite the challenge....
MR. Organic Chemistry Tutor, thank you for a powerful illustration on How to Solve Mutiple Triangle Trigonometry Problems. These are well known problems in Trigonometry.
for some reason, the equation of y (tan 43) = (80 + y) tan 35 (14:11) comes out as 241.131 when put directly on calculator, but 240.86 comes on calculator when done manually
Easier method for last one: solve for the base represented interms of x by doing : tan^-1 35 then find y (in terms of x, as marked in the video) by replacing 35 with 43. Now you should have the length of the base and the length of y, both as fractions/multiples of x. Finally subtract the ladder from the former, divide the result by 80 and take the reciprocal. Strangely however my calculator says the answer is 224.85, so either it’s a rounding error or I’m doing something wrong 😅
Nice video, i do not have a trig. calculator, so i solve the missing sides in AutoCad 2010 . AutoCad and trig calculator has the same calculate system.
@@maymiller3639 True... There are all sorts of complex variations, but generally at GCSE maths (O levels), the above is as hard as it can get. Sure at A level and Pure/Applied maths, such a problem is possible. I've examined numerous GCSE maths papers and have not see more complex Trigonometry 📐than this! Looks like there is sadly no exams in 2020 (only assessment) because of Covid-19 🔅!
So I followed step by step and for the final answer I got 224.9 when put to one decimals place and when moved to two places it is 224.85. Do you have any suggestions I could use to get a closer answer closer to yours? Keep up the great work!
Can you provide some finance applications where this could be used? I understand the concept but do not understand the application of where this specific example can be used.
Is there a way to get the answer by percentage? For instance, tan35 + tan43 and using that number to find the percentage difference of both? One is ~57% the other is ~43%
really quickly could you explain why you could not break the two triangles already made on 8:20? is it because the angle 25 doesnt go to the side in the middle? only to the side 400?
just wannna ask if my answer is valid although i have a slightly different answer? i copied every single decimal value so my answer fall to 241. 1312227 for the 3rd example.
I'm no math expert, I do know he made a mistake in the second example...tangent is equal to opposite over adjacent, NOT hypotenuse and the hypotenuse is not 200 because the hypotenuse isn't given....I'm starting to realise that it was just a little mistake😅
It seems to me as though you are the one who made the little mistake. You're right in sayingg that tangent is opposite/adjacent, however the side opposite to 30 degrees just so happens to be the hypotenuse, and yes, the hypotenuse can be the opposite side to an angle! Therefore, it is indeed h2/200.
hey guys, can anyone help me with this? From the top of the building, the angle of depression of a point in the same horizontal plane with the base of the building is observed to be 47°18'. What will be the angle of depression of the same point when viewed from a position halfway up the building?
whyy? I'm from Turkey and I am curious about the education system of other countries. 17 years old children in our country see much more of these lessons and have difficulties. How is your education system?
Hey, idk if someone will read this, but I wonder what should I do when there are two right triangles but bond at the end in front of each other. Like 📐🗡️ with special angles of 30 and 60

*salutes* Literally the best at explaining!
that last triangle was the hardest and I had a problem like this,
thank you for teaching me the order I think I understand the whole of it now.

Thank you so much!!! x=80[(tan(43°)*tan(35°))/(tan(43°)-tan(35°))]=80*(2.8107)=224.856
MR. Organic Chemistry Tutor, thank you for a powerful illustration on How to Solve Mutiple Triangle Trigonometry Problems. These are well known problems in Trigonometry.
Finally, found a clear explanation for that last problem. Thanks so much
Honestly thank u so much my teacher is shit at explaining this but you really cleared it up for me. I feel much more confident about my test now lol
Your teacher needs to work on explaining because it's serious since she is a teacher
Same tho😭
what can you do school hire shit teacher for less salary shitty as economy
Thanks a bunch
You helped alot

What the sigma
Bro that last example just killed me i need to practice more to understand. Also don't we round off numbers only when getting the final answer
Thank yu sm....yu just saved my life
Alot of appreciation from Ethiopia 🇪🇹
You are best I've ever known!
Thankyou!
You are the best!
Thankyou so much my gentle man!

you made me understand like 10 hr of lecture watching in like 2 hrs as u skip right to the chase and do the work ;D
Your the goat of math man
That last one really pushes Trigonometry to a new level and if you can solve that, you can crack any problem!
thatsnot true unfortunately try 3D problems then youll be able to do any maths its so hard

How do we get 671.3 from 800 tan 40*
without rounding, tan40 x 800 is 671.2797049, however rounding to the nearest tenth would be 671.3
So I followed step by step and for the final answer I got 224.9 when put to one decimals place and when moved to two places it is 224.85. Do you have any suggestions I could use to get a closer answer closer to yours? Keep up the great work!
Make sure your calculator is in degree
I also got 224.85. I think he might have done a rounding error or just different calculators or something
I got 277.86.
Thanks! I needed to brush up on my high school math for physics class lol
Thanks a lot sir .Your videos are always helpful to me .
Great stuff mate!
Trigonometry is fun!
Can you provide some finance applications where this could be used? I understand the concept but do not understand the application of where this specific example can be used.
Thank you ❤️
You are the MAN!
In South Africa we don’t pay attention in maths class…… coz we know Kevin got us 😭🫶🏽❤️🔥
Thanks for sharing the video
Hi please do an example to find missing angles working with more then one triangle🙏
1st problem without knowing the answer:
Tan(40)×800 + Tan(30)×800
Wow. Than you. Great video
Who are you I can’t believe you are doing this
what if it doesn't have the adjacent sign at H2 for first part of your example what should I write then?
idk
For the problem at 6:30, isn’t it faster to use the top vertex? Tan65(400) - Tan55(400)? Gets the same answer.
Is there a way to get the answer by percentage? For instance, tan35 + tan43 and using that number to find the percentage difference of both? One is ~57% the other is ~43%
Nice tutor 👍👍😎🤗
Thank you so much!!!! 💜💜💜💜💜
Lost me after 2 minutes ngl
really quickly could you explain why you could not break the two triangles already made on 8:20? is it because the angle 25 doesnt go to the side in the middle? only to the side 400?
Hi. Back again
Where did 800 came?
From the opposite of the angle 40
My question was a bit different but I got how to do it thnx
in the 1st example, how to find the distance when its not given?
Thank you soooo muchhhh
in problem 6:25, what do i do if the angles are not on the bottom, instead they're at the top, beside the dividing line? thank you po
Last example could be done using Law of sines. Only two steps to solve.
just wannna ask if my answer is valid although i have a slightly different answer? i copied every single decimal value so my answer fall to 241. 1312227 for the 3rd example.
thats not correct, it should be 224.841963
which is very close to 225 you should be able to write 225
How did you get the 671.3?
6 years later and I still don't understand how to do this. This is why I give up
I hope you have found what you love and understand in life. We all have different abilities, that is alright, no one is the same. God bless you
You mixed up the opposite angle with the hypotenuse
Why am I getting negative 5.1 for 800 tan 30 degrees
Your calculator is in radian mode when it must be in degree mode
I'm no math expert, I do know he made a mistake in the second example...tangent is equal to opposite over adjacent, NOT hypotenuse and the hypotenuse is not 200 because the hypotenuse isn't given....I'm starting to realise that it was just a little mistake😅
It seems to me as though you are the one who made the little mistake. You're right in sayingg that tangent is opposite/adjacent, however the side opposite to 30 degrees just so happens to be the hypotenuse, and yes, the hypotenuse can be the opposite side to an angle! Therefore, it is indeed h2/200.
What about two triangles but both of the angles are only on one triangle?
hey guys, can anyone help me with this?
From the top of the building, the angle of depression of a point in the same horizontal plane with the base of the building is observed to be 47°18'. What will be the angle of depression of the same point when viewed from a position halfway up the building?
still need help?
Hello, quick question: how do I know the 'sum' and when do I know to subtract?
If any of ya'll have a clue please let me know..😊
I'm kinda struggling to understand the question but all I can say is learn the formula's and then learn how to rearrange it
thank youuu
Uhhh i am confused in h1 Part 1:53 please tell me how you got that!!!
You have to multiply the tan(40) by 800 so you can get the length or height using Tan in this case.
tan(40)=h1/800 becomes h1=800tan(40). And then u just solve to get the height.
I thought adjacent is the bigger side?
im lost after 3 mins
XD same
Myyy other triangle doesn’t have no angle number
Boyle sorular simdi kolay olmuslar bana.
Sorry but am getting 0.474 when I put tan 35 in my calculator using rad mode!
Change the calculator to Degrees mode NOT Radian! Thats normally the preferred default.
Then, Tan 35° = 0.70
You need it in degrees
@@ksumar Thanks much.
HIHI MATH SPEEDRUN TIME !! DUDUDUDU
thank you
I don't understand how he get 81030 and 81040
E
I got same answer for last one but I used law of sines
This is why I don’t use math pug🙃
Wtf my calculator is giving me wrong answers plz help me I have exam today 😭
Hassan Sohaib make sure your calc is In degree mode
Lol
You talk to fast slow down
You can slow down the speeed
