Question

∠A and ∠B are complementary angles of right triangle ABC, cos A = 0.83, and cos B = 0.55. What is sin A + sin B?

A) 0.28

B) 1

C) 0.38

D) 1.38

Answer 1

Complementary angles
A+B=90 degree
and sin A = cos B
cos B = sin A

Answer 2

Soo.. the answer iss... ? Lol.

Answer 3

sin A = cos B = .55
sin B = cos A = .83
so sin A + sin B = .55 + .83

Answer 4

Whatever.. i'm guessing.

Answer 5

its D...omg =))
