Question

Pretty please help meeee

Answer 1

∠ B ≈ 72°

Explanation:

Using the tangent ratio in the right triangle

tan B =
`(opposite)/(adjacent)` =
`(AC)/(AB)` =
`(9)/(3)` = 3 , thus

B =
`tan^(-1)`(3) ≈ 72° ( to the nearest degree )

Answer 2

C= 72

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.
