We have the following:
We can see that it is a right triangle, since it has a right angle, which means that we can apply a trineometric ratio. In this case we can apply the sine function that relates the opposite side and the hypotenuse, both known values:
[tex]\sin \theta=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]
replacing:
[tex]\begin{gathered} \sin \theta=\frac{36}{60} \\ \theta=\sin ^{-1}\frac{36}{60} \\ \theta=36.87\cong37 \end{gathered}[/tex]
Therefore, the answer is B) 37°
