Question

For the right triangle shown, which of these equations is correct?

1. all answers are correct
2. cos(53) = x/16
3. cos(53) = sin(37)
4. sin(37) = 16/x

Answer 1

3. cos(53)=sin(37)

Explanation:

let y be the third side

cos(53)= adj/hyp

=y/16

sin(37)=opp/hyp

=y/16

therefore, sin(37)=cos(53)=y/16

Answer 2

3

Explanation:

3 because 37° and 53° these sum is 90°.
