Which equation can be used to solve for c?

Triangle A B C is shown. Angle A C B is 90 degrees and angle A B C is 35 degrees. The length of C B is 5 inches, the length of A C is b, and the length of B A is c.

c = (5)cos(35o)
c = StartFraction 5 Over cosine (35 degrees) EndFraction
c = (5)sin(35o)
c = StartFraction 5 Over sine (35 degrees) EndFraction

Use cosine with angle B (35°): cos(35°) = adjacent/hypotenuse = 5/c, so c = 5 / cos(35°).
