Question

If A and B are complementary angles, then
A. sin A = sin B
B. cos A = cos B
C. tan A = tan B
D. sec A = cosec B

Answer 1

Answer:

C ............ ........

Answer 2

D. sec A = cosec B

Step-by-step explanation:

Two Angles are Complementary when they add up to 90 degrees.

If A and B are complementary, A = 90-B and B = 90-A

We know the identity Sec A = Sec (90-B) = Coses B

So Option D is the answer.
