Question

Find the angle of elevation that the beam should be aimed to go through the hole.

Answer 1

We can find the angle x using the tangent function:

`\begin{gathered} \tan (x)=(opposite)/(adjacent) \\ so\colon \\ \tan (x)=(11)/(36) \\ x=\tan ^(-1)((11)/(36)) \\ x\approx16.99^(\circ) \end{gathered}`
