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 72degree, and Brisa is holding the kite 1.2 m off the ground. How high above the ground is the kite flying? (Round to the nearest meter)

Answer 1

The height the kite is flying above the ground level to the nearest meter is 42m.

Explanation:

this is not drown to scale:

Angle is 72º

sine = opposite / hypotenuse

sin 72 = x / 43

0.9510565 = x / 43

therefore x = 40.9m

Brisa is holding the kite 1.2 m off the ground, we also need to add 1.2 m to our calculated height of the kite. Thus, the answer is

40.9 m + 1.2 m = 42.1 m to the nearest meter is 42m.
