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

We can find the angle x using the tangent function:
[tex]\begin{gathered} \tan (x)=\frac{opposite}{adjacent} \\ so\colon \\ \tan (x)=\frac{11}{36} \\ x=\tan ^{-1}(\frac{11}{36}) \\ x\approx16.99^{\circ} \end{gathered}[/tex]
