select the true statement about triangle abc?

[tex]Sin\frac{opposite}{hypotenuse}Cos\frac{adjacent}{hypotenuse} Tan\frac{opposite}{adjacent}[/tex]
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
