Answer:

58.2 degrees

Step-by-step explanation:

The given problem is illustrated using the diagram below:

The angle the ramp makes with the sidewalk is labeled x above.

Using trigonometry:


\begin{gathered} \sin x=(17)/(20) \\ x=\arcsin ((17)/(20)) \\ x=58.2\degree \end{gathered}

The angle the ramp makes with the sidewalk is 58.2 degrees.
