Select the correct answer from the drop-down menu.
tant = . Therefore, tan(90-A) =
(All angle measurements are in degrees.

Step-by-step explanation:

The choices to this question are

a.) 1/tan(90-A)

b.) 1/sin A

c.) 1/cos(90-A)

d.) 1/tan A

We know that

, which is a trigonometric identity.

If then,

But, and

So,

Which is the inverse of tangent, so

Therefore, the right answer is D.
