Question

Which equation can be used to find the measure of angle BAC? A.) inverse tan (5/12) B.) inverse cos (5/13) C.) inverse sin (12/5) D.) inverse tan (12/13)

Answer 1

B

Explanation:

The angle that has tan 5 / 12 is ∠ABC so A is not the answer. The angle that has cos 5 / 13 is ∠BAC so B is the answer.
