If Jack knows the hypotenuse of a triangle, but is trying to find the opposite side of a right triangle, would he use Sine, Cosine, or tangent? Why?
He would use Sine, because sine is opposite/hypotenuse so he can solve for O. However, he can not use tangent because he does not know the adjacent side.
a/Sin a = b/sinb = c /sinc
