Question

A kite on 100-foot string is fastened to the ground, making a 25 degree angle with the ground. To the nearest tenth of a foot, how high above the ground is the kite.Required to answer. Single choice. (6 Points)24.642.346.690.6

Answer 1

Using the trigonometric function sin we get:

$\begin{gathered} \sin 25^{\circ}=\frac{x}{100\text{ ft}} \\ \text{Solving for x} \\ x=100\text{ ft(}\sin 25^{\circ})\approx42.3\text{ ft} \end{gathered}$

Then the answer is 42.3
