Find m
2B, rounded to the nearest degree. Please help me

Answer:
∠ B ≈ 53°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan B = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{4}{3}[/tex] , then
∠ B = [tex]tan^{-1}[/tex] ([tex]\frac{4}{3}[/tex] ) ≈ 53° ( to the nearest degree )
