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.

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

excellent explanation

thanx lot ..

Good explanation

Thanks

Thank you mam

Height/base equals tan of this angle And base equals height divided by tan theta 20/tan(30) equals 20*1.732 # 34.64

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

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

Class 11th trigonometry function chapter video

cot 30*= adjacent/opposite or, √3 = BC/AB or, √3 = BC/ 20 ∴ BC= *20√3* (Ans)
