Ineed to know the answer to this promblem

Hello.

To find the value of the angle x, you need to use the Law of Sines. The Law of Sines states, sin A / a = sin B / b = sin C / c.

We are given sin A = 42 degrees, side a = 22 cm, and side b = 12 cm. We can change x, to angle B in this case.

sin (42) / 22 = sin B / 12 (multiply both sides by 12)

12 sin (42) / 22 = sin B

sin^-1 B = 12 sin (42) / 22

sin B = 21.4063..

The measure of angle x is equal to about 21.4 degrees.
