Question

find the height of the building to the nearest foot.

Answer 1

In this problem we can use the trigonometric identities to find the hight so we can use the sin identiti:

$\sin (\theta)=\frac{oposite}{hypothenus}$

So in our problem will be:

$\sin (63)=\frac{x}{220}$

and we solve for x so:

$\begin{gathered} 220\sin (63)=x \\ 196=x \end{gathered}$
