This has been the MOST helpful geometry video I’ve seen for the SAT. I am 100% honest when I say that before this video I could not solve the highest difficulty geometry problems, but now that I understand the concepts it’s so easy
took the SAT a few months back and got a really disappointing score on the math purely because I had forgotten all of the middle school triangle stuff (all of the angle and side congruency rules). I did amazing on everything else. taking it again in a few days and that's definitely not happening again!
@empoweredsuccess it doesn't matter that he used sin(c) because sine C and sine F are both equivalent angles. if you solve using the sides from triangle DEF you will notice you get the same answer as if you solve using ABC.
Well, he just assumed that you can take it as 40-40 or 50-50. Anything is fine. He just assumed it .he just wanted to tell you that sin and cos of an angle are to equal
for the qn 20th, i solved by a diff way for which i got my ans in decimal i.e 0.66 which is 3/5 (the ans u got was 3/5) so wht i wanna ask is if answers in decimals are allowed?
I just passed my international dsat, literally like an hour ago and I got the almost same question like in 2:46 but the thing is, the 114 one was an X and the X one in video was 28, 31->43 and I couldn’t solve for X, still sitting with this one even after my exam is over(
It doesn't matter what he put, it could've been 80-80 or 25-25 or anything else. He's just saying that apparently when you are taking sin of an angle, cosine of the angle next to it is the same thing. Kind of confused me to
no its right AE which is 18 refers to the entire triangle ACE therefore you dont have to add 10 so 30 is correct. If you are confused or dont believe me there are other videos that do this problem ruclips.net/video/wXMQlY853A0/видео.html

Glad to help!

Jesus Christ loves us unconditionally+eternally!He cares for us so much that He sacrificed Himself on the cross for our sins!God is so good!💗✝️
For question number 20 on the Trig problems, it asked to solve for Sine F, while you solved for Sine C, Great video anyway!!

bro you are literally awesome! This is the most useful information I have ever learned out of my 11 years of schooling!
what the hell were you doing in geometry class?
GOD BLESS you! Thank you so much!
this is a life saver thank you so much
Great video! Really helped me.
You’re awesome Thank you so much!!!
I thought 18 should be 40? bc x=30 would correspond to line DE, while line CD equals 10, so 10+30=40
Your the best teacher
thank you very much your a big help 👍🏼
Is 20 correct ? I think U have fined only sinC
I don’t understand why sin/ cos is 50 degree???
Well, he just assumed that you can take it as 40-40 or 50-50. Anything is fine. He just assumed it .he just wanted to tell you that sin and cos of an angle are to equal
20 is wrong its 3/5. i checked all wesbites
18 is 40 right?
for the qn 20th, i solved by a diff way for which i got my ans in decimal i.e 0.66 which is 3/5 (the ans u got was 3/5) so wht i wanna ask is if answers in decimals are allowed?
Do believe they are

omgg i’m still thinking about it because i couldn’t solve it and now my whole family is trying to figure it out
Thank you so much!!
Nice and informative 👍bro stay tuned
Fine and great
is this all the geo we need to know or is there more???

Score +1450 on the SAT with my channel's content!
I think number 20 is 3/15 since F is 1/3 of C
it’s a ratio bc the triangles are the same, the second triangle isn’t even necessary for the problem, they just use it to trick people
sorry the triangles ratio is the same, the triangles themselves are not the same
@@pixally591 The word you’re looking for is “similar triangles” which refers to triangles having the same ratios.
no bc 1/3 of 12 is 4 and 4 * 3/20 (sin) = 3/5

66-2=64
180/90=2
10:13 why did you d 50-50
It doesn't matter what he put, it could've been 80-80 or 25-25 or anything else. He's just saying that apparently when you are taking sin of an angle, cosine of the angle next to it is the same thing. Kind of confused me to

that's what I thought too
no its right AE which is 18 refers to the entire triangle ACE therefore you dont have to add 10 so 30 is correct. If you are confused or dont believe me there are other videos that do this problem ruclips.net/video/wXMQlY853A0/видео.html
@@derpyhuman1583 Oh I just realized my mistake. Thanks for pointing it out. Yeah it has to be 30.
