Answer:
x ≈ 31.0°
Step-by-step explanation:
From the right triangle given in the picture,
By applying tangent rule,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{9}{15}[/tex]
x = [tex]\text{tan}^{-1}(\frac{9}{15} )[/tex]
x = [tex]\text{tan}^{-1}(0.6)[/tex]
x = 30.96
x ≈ 31.0°
Therefore, measure of angle x is 30.0°
