Question

Brisa's kite is flying above a soccer field at the end of 43 m of string. If the angle of elevation to the kite measures 72, and Brisa is holding the kite 1.2 m off the ground. How high above the ground is the kite flying?

Answer 1

Hi Zoe, using the information given, the length of the string, 43 meters, and the angle of elevation, 72 degrees, we can compute the height of the kite above ground, not including the height Brisa is holding the string.

Let x represent the height of the kite without the height Brisa is holding the string.

x * sin 72 = 43

Solving for x gives, x = 43 / sin 72, or x = 45.21 meters.

Adding the height Brisa is holding the string, 1.2 meters to 45.21 meters gives a total of 46.41 meters.
