Answer:

m∠X ≈ 41.3

Explanation:

This is what I did!

Find the length of the side opposite X; solve the smaller right triangle using the Pythagorean theorem:


8^(2) +S^(2) = 22^(2) \\

S ≈ 20.49

Use the SINE ratio (opposite leg/hypotenuse)


sinX = (20.49)/(31) \\X = 0.660\\

Use the INVERSE SINE ratio to find the measure


sin^(-1) (0.660)

m∠X ≈ 41.3
