Question

Select the correct formula to solve for x.

cos (33) = x/14
sin (33) = x/14
cos (33) = 14/x
sin (33) = 14/x

Answer 1

The answer is B. Cos(33)

Answer 2

Answer: Choice B) sin (33) = x/14

This is because the sine of an angle is equal to the opposite side over the hypotenuse

sin(angle) = opposite/hypotenuse

sin(33) = x/14

We can't use cosine because we don't have a variable for the adjacent side.
