Answer:
58.2 degrees
Explanation:
The given problem is illustrated using the diagram below:
The angle the ramp makes with the sidewalk is labeled x above.
Using trigonometry:
[tex]\begin{gathered} \sin x=\frac{17}{20} \\ x=\arcsin (\frac{17}{20}) \\ x=58.2\degree \end{gathered}[/tex]
The angle the ramp makes with the sidewalk is 58.2 degrees.
