The hypotenuse is the longest side of the triangle. The opposite side is the side across from a point/angle. The adjacent side is the side next to the point.

At point A, AC is the hypotenuse, BC is the opposite, AB is the adjacent.

cos A = 12/13

A.) sin C = 12/13   This is the answer

B.) sin B, the opposite is 13, and the hypotenuse is 13

C.) tan C = 12/5

D.) cos C = 5/13

answer: procent 54 wynosi 33,33%
