Question

A child is standing at point c and flying a kite located at point a, 25 ft above the ground. as the child lets out more string, the kite rises to a point b, directly above point
a. if the angle of elevation changes from 50º to 65º, how much higher to the nearest foot, is the kite than it was initially?

Answer 1

To solve this problem you must apply the proccedure shown below:

 1. You have that:

 - The kite is located at point 25 ft above the ground.
 - The kite rises to a point b, directly above point a.
 - The angle of elevation changes from 50º to 65º.

2. Therefore, you have:

 25 feet/50°=0.5 feet

 x=(0.5 feet)(65°)
 x=32.5 feet≈33 feet

 3. Then, as you can see, the answer is: 33 feet.
