Question

22) Find the measure of angle B.

Answer 1

Answer: Approximately 51.06 degrees

Work Shown:

`\sin(\text{angle}) = \frac{\text{opposite}}{\text{hypotenuse}}\\\\\sin(\text{B}) = \frac{\text{AC}}{\text{AB}}\\\\\sin(\text{B}) = (7)/(9)\\\\B = \sin^(-1)\left((7)/(9)\right)\\\\B \approx 51.0575587^(\circ)\\\\B \approx 51.06^(\circ)`
