52.1º

1) As we have a right triangle, then we can make use of a trigonometric ratio sine and the arcsine:

$\begin{gathered} \sin (\theta)=\frac{opposite\text{ leg}}{\text{hypotenuse}} \\ \sin (\theta)=(15)/(19) \\ \end{gathered}$

2) Let's calculate the arcsine of 15/19 to get the angle measure:

$\begin{gathered} \theta=\sin ^(-1)((15)/(19)) \\ \theta\text{ =52.1363}\approx52.1 \end{gathered}$

3) As the measure of the angle is given either in radians or degrees, then the answer is 52.1º
