Answer:
150.90 feet
Explanation:
It is given that,
A kite is flying 99 ft off the ground
The angle of elevation is 41°.
We need to find the length of the string. Let it is H.
Here, 99 ft is the perpendicular of a right angled triangle. We need to find hypotenuse of the triangle. Using trigonometry we can find it as follows :

So, the length of the string is 150.90 feet.
