Homework Help: trig

The terminal side of an angle includes the point (5,-12). Give the sine, cosine, and tangent of the angle exactly.

I know how to plot it and everything, but I'm not sure where to put theta so I know which angle to use for finding sine, cosine, and tangent. I think it has something to do with the terminal side, but I'm not sure. Could someone please explain it to me.

Put theta between the positive x axis and the ray going from the origin to the point.
