Trigonometry can be used to measure the height if you know the distance from where you observe the building and the angle of elevation you can easily find the height of the building. Similarly, if you have the value of one side and the angle of depression from the top of the building you can find and another side in the triangle, all you need to know is one side and angle of the triangle.

For any 30-60-90 degree triangle, the short side of the triangle (the side opposite 30 degrees) times the square root of 3 equals the length of the medium sized side (the side opposite 60 degrees). Therefore, 20 (the length of the shirt side) times the square root of 3 equals the length of the side we’re looking for

To remember trigonometric ratio I’ll tell you a easy trick Just remember “OHAHOA” The first oh stands for sin s ratio ie, opposite side by hypotenuse and ho for cos s ratio ie adjacent by hypotenuse then oa for tan When you reverse the word aohaoh you’ll get the remaining for cosec sec and tan Thank me later
I think there is a lesson for determining the degrees of the angles. For example, 90° is the right angle which is the very simplest form of angle. 45° is the half of 90° so I assume you can visualize it. As for 30° angle, there is another topic for that by solving and knowing some formula

Short and sweetly explained
For any 30-60-90 degree triangle, the short side of the triangle (the side opposite 30 degrees) times the square root of 3 equals the length of the medium sized side (the side opposite 60 degrees). Therefore, 20 (the length of the shirt side) times the square root of 3 equals the length of the side we’re looking for
Solution for cot C=BC/AB
Cot 30°=BC/20
√3=BC/20
20√3=BC

WOWW....I'm doing regret why i don't get this Awesome channel first ......Amazing explanation ma'am

Awai 🤗
Height/base equals tan of this angle
And base equals height divided by tan theta
20/tan(30) equals 20*1.732 # 34.64
mashallah u explained so clearly thx
Inshallah boy played well
@@s.jadhav6261 girl imao what boy
یار جی اس سے اچھی ٹرگنومیٹری تو مجھکو آتی ھے
یہ تو confusing ھے
Thank u so ooooo much dont memorise thank u thank u thank 💓 💗 💖 💛 💕 😌 💓 💗 💖 💛 💕 😌 💓 💗
excellent explanation
Good...... 👍
Superb explanation
👍
Thank you so much.
Happy Learning :)
CotC=BC/AB
Cot30=√3
BC/20=√3
BC=20√3
Vertical means adjustant
ty mam 💚💛💜👍
Thanks
Is there any part -2 video is this please tell me
where is the part two of this
Good explanation
Thank you mam
Thank u
Thanks a lot
You're welcome. Happy Learning :)
Good explanation Do you have a apk?
A good explanation but I don't understand this topic
What is meaning of root3?
Ans is BC(Adjacent)or =34.6410m
cot 30*= adjacent/opposite
or, √3 = BC/AB
or, √3 = BC/ 20
∴ BC= *20√3* (Ans)
Super
thanx lot ..
Keep it up,😘
why did the formulae for cos change from adjacent by hypotenuse to adjacent by opposite
Cot30 = BC/AB, (cot30 = √3)then,√3 =BC/20 , so our answer is 20√3😀😀

To remember trigonometric ratio I’ll tell you a easy trick
Just remember “OHAHOA”
The first oh stands for sin s ratio ie, opposite side by hypotenuse and ho for cos s ratio ie adjacent by hypotenuse then oa for tan
When you reverse the word aohaoh you’ll get the remaining for cosec sec and tan
Thank me later
Wow create idea
This can also b remembered as SOME PEOPLE HAVE CURLY BLACK HAIR TO PRESENT BEAUTY
When you reverse it you get cot not tan 😄
@@rashidamintoo5775 How ?
Or say SOH, CAH ,TOA
Sin opposite over hypotenuse
Cos Adjacent over hypotenuse
Tan Opposite over Adjacent
Ans is 34.64. 😊
Can you explane me angles in degrees
Hello! You will find videos on angles here: dontmemorise.com/course/view.php?id=36
Enjoy!
Where is the part 2
It's a waste of time to search for it
Learn to provid adequate info of all the parts
angle of elevation video is part two
Can someone please tell me where part 2 is 🙄🙄
Privated
Hame PTA kese chalega sine ya tan Lena h? 🤔🤨

Yes pls make a video on trigonometric identities
You say this application is for the real world but how we get the angle30° ??!!
I think there is a lesson for determining the degrees of the angles. For example, 90° is the right angle which is the very simplest form of angle. 45° is the half of 90° so I assume you can visualize it. As for 30° angle, there is another topic for that by solving and knowing some formula
34.64m
34.64 metres
my calculator shows tan(30)=
Root over 3 by 3
:(
Simplify it further
Cot 30 =3^1/2
Cot 30=BC/AB
3^1/2=BC/20
3^1/2×20=BC
Verified
beautiful
what is e in e(AB) = 20cm, pls reply any one who knows answer
that is L(length) not e😅

Hopefully, they also publish English lessons so that you can at least be good at that.

Ok Good
tan30 = 1/√3, how? 🤔
Look at trigonometric table
@@pranavb2k 😂
if u simplify it u will get 3/3√3 then simplify it again it will became 1/√3
