x ≈ 31.0°

Step-by-step explanation:

From the right triangle given in the picture,

By applying tangent rule,

tan(x) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(x) = $\frac{9}{15}$

x = $\text{tan}^{-1}(\frac{9}{15} )$

x = $\text{tan}^{-1}(0.6)$

x = 30.96

x ≈ 31.0°

Therefore, measure of angle x is 30.0°
