Answer:
22.470
Step-by-step explanation:
In this example you have to use the trigonometric function sine which is defined as
Plug in known values:

Multiply both sides by 25

Approximate sin(64) using a calculator:

Simplify

We can use the Sine Law:
a / sin A = b / sin B
16 / sin 22° = 25 / sin B
16 / 0.3746 = 25 / sin B
sin B = 25 · 0.3746 / 16
sin B = 0.5853
∠B = sin^(-1) 0.5853
∠B = 35.83° ≈ 35.8°
Answer: b. 35.8°
