Answer:

Measure of the unknown angle is 21°.

Step-by-step explanation:

In the given question,

Measure of opposite side and the measure of hypotenuse have been given.

Therefore, we will use the trigonometric ratio for the unknown angle which has the ratio of opposite side and the hypotenuse.

$\text{sin}\theta=\frac{\text{Opposite side}}{\text{Hypotenuse}}$

$=\frac{13}{36}$

$=0.36111$

$\theta \approx \text{sin}^{-1}(0.36111)$

$\theta \approx 21.17$

$\theta \approx 21^{\circ}$

Therefore, measure of the unknown angle is 21°.
