Answer:

C= 72

Step-by-step explanation:

Because if AB=3 and AC= 9 and you solve and find all the side lengths you will get 71.565 for m<B and you round to the nearest degree its 72. Hopefully this helps you and you get it right. But I'm 100% it is 72.

Answer:

∠ B ≈ 72°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan B = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{9}{3}[/tex] = 3 , thus

B = [tex]tan^{-1}[/tex](3) ≈ 72° ( to the nearest degree )
