Use an inverse trig function to find the missing angle measure. Round your answer to the nearest tenth (first decimal place)

Answer:
x° ≈ 51.1°
Step-by-step explanation:
In this geometry, you are given the side opposite the angle, along with the hypotenuse. The relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(x°) = 14/18
x° = arcsin(14/18) ≈ 51.0576°
x° ≈ 51.1°
