Question

Someone help please

1= 39 degrees
2: 40 degrees
3: 41 degrees
4: 42 degrees

Answer 1

A

Explanation:

This uses the sine law.

Sin(theta)/113 = sin(42)/120 Multiply both sides by 113

sin(theta) = 113*sin(42)/120

sin42 = 0.6691

sin(theta) = 113 * 0.6691 / 120

sin(theta) = 0.630008

theta = sin-1(0.63008)

theta = 39.1 Looks Like A
