Question

PLEASE HELP ME

Consider this right triangle.
Determine if each expression is equivalent to the length
of AC. Select Yes or No for each expression.
Yes
No
13sin(B)
13cos(A)
12tan(A)
12tan(B)

Answer 1

YES, YES, NO, YES

Explanation:

Cos angle = adj/hyp

Sin angle = oppo/hyp

Tan angle = oppo/adj

Sin B = AC /13.

AC = 13 sin B. This YES

Cos A = AC/13

AC = 13 cos A. This YES

Tan A = 12/AC

AC = 12/ tan A. This is NO

Tan B = AC /12

AC = 12 tan B. This is YES
