Question

1) You're flying a kite that is 200 foot high from the point, N on the ground.

The kite string makes a 50° angle from the ground (point M), find the length MN

Answer 1

Explanation:

`(200)/(MN) =tan~50\\MN=(200)/(tan~50)\\=200 cot~50\\=200 ~cot(90-40)\\=200 ~tan~40\\\approx 167.82~foot`

tan (90-x)=cot x

cot(90-x)=tan x
