Answer:
9.0, B
Step-by-step explanation:
Remember: SOH CAH TOA
sine is opp/hyp, cos is adj/hyp, and tan is opp/adj
In this case, you want to use tan because the sides you want to work with are the opposite and adjacent sides.
The opposite side is x, and the adjacent side is 12.
tan(x)= opp/adj
tan(37°)= x/12
12(tan(37°))= x
12(0.75))= x
9= x
So, the answer is 9.0, B.
