Question

Anne watches as her kite rises and comes to a stop at an unknown height. The string attached to her kite has a length of 39 feet and the angle of elevation of the kite from where Anne is currently standing is 65. How far is the kite off the ground?

Answer 1

The kite is at a height 35.35 feet.

Step-by-step explanation:

Refer the given figure,

BC = Length of string = 39 feet

∠B = 65°

We need to find height of the kite , that is AC = h

We have

`sinB=(AC)/(BC)\\\\sin65=(h)/(39)\\\\h=39* sin65\\\\h=35.35ft`

The kite is at a height 35.35 feet.
