Question

please help me solve the rest, I get to sin A = 7/22 but then dont know how to solve that to get my final answer, thank you!

Answer 1

Given:

The height is 7 ft.

The length of the ramp is 22 ft.

To find the angle:

Using the trigonometric ratio,

`\begin{gathered} \sin \theta=\frac{Opp}{\text{Hyp}} \\ \sin \theta=(7)/(22) \\ \theta=\sin ^(-1)((7)/(22)) \\ \theta=18.55 \\ \theta\approx18.6^(\circ) \end{gathered}`

Hence, the angle is 18.6 degrees.
