Question

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

Answer 1

x° ≈ 51.1°

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°
