Answer 1

Answer:

cosB

Step-by-step explanation:

Acc. to given information A+B=90°

A=90°-B

sin A = sin (90°-B)

sin A = cos B

PLEASE MARK THIS ANSWER AS THE BRAINLIEST ANSWER

Answer 2

Answer:

A and B are complementary angles that means the sum of those two angles is 90°

A + B = 90°

A = 90° - B

sinA

sin ( 90-B )

cosB

therefore sinA = cosB

i think this is the answer............I hope this helps u
