Step-by-step explanation:
So we want to find<em> θ. </em>We are already given the hypotenuse and the side length opposite to <em>θ. </em>Therefore, we can use the trig function sine to find <em>θ. </em>
Recall that:

Plug in 10.2 for the opposite side and 15 for the hypotenuse:

Solve for <em>θ. </em>Use a calculator:

The answer is D.
