Sir pls do a video on triangles it’s a bit difficult and I like your videos
I'll try to put more Maths videos soon!!
Sir tq for your best videos. Before i was very poor in mathematics 😌but now I can able to answer any type of questions really they are very helpful sir thank you thank you so much sir
Happy to help
Sir the answer is 300 m/s where x=1500m and y=1500m so, x+y=1500+1500=3000m then by the formula speed=distance/time, time is given 10s and distance 3000m=3000m/10s=one 0 is cancel 300m/s answer....
Our manocha sir is an all rounder
Thanks. Glad to hear that.

Sir ur teaching is awsome
Thanks a lot 😊
If it is a tringle with 30°:60°: 90°
The opposite side's ratio= 1:√3:2
And for 45°:45°:90°
Side's ratio=1:1:√2
In ∆BAD,
tan(angle D)=Opposite/Adjacent
Or,tan(angle D)=AB/AD
From the trigonometric table,
tan(30°)=1/√3
Or,75/AD=1/√3=75√3=15m
In ∆BAC,
tan(45°)=1
Or,AB/AC=1
Or,75/AC=1
Or,AC=75m
Or, Distance between two ships=AC-AD=75-15=60m

Sir thank you tomorrow my test is there on heights and distances and i was scared what to do but now my concept is totally clear. THANK YOU SIR !!!!
All the best
@@ManochaAcademy Thank You Sir 🙏🏻🙏🏻
First position of plane has distance from the point of observation equal to 1500 m and after 10s the distance from observer equal to 4500m and to find speed v need to use d/t formula. Time will be 10s and distance moved at the time is 4500-1500 =3000. Now substituting on formula 3000/10 we get 300m/s as answer
Nice teaching and neat handwriting
🙏🙏
Thanks I understand the chapter clearly.
It's my pleasure
@@ManochaAcademy 😊🙏🙏
legends watch this video a day before exam
Bro Mee to bro I have tommorow exam

No I have today
Bro i have an exam in an hour and I am watching now
@@amitjoel4487 bro i am giving the exam 🤣
I am very happy to find a great teacher
🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
It's my pleasure
First we have to find the length between point of observation and the plane before the trip ,then we find the length between point of observation and the plane after the trip. Finally dividing it by the time we get 300m/s. Isn't it?
Visualization study is love😂😂😂😂
I have studied this video completely for the aema final interview and thanks alot now i am cleared the interview.....
Thanks alot sir for your wonderfull class. 💝
