Which leg on the tangent?

When I set up the ratio for the tangent, how can I tell which leg to use for the adjacent leg, on the bottom of the ratio?

I just can't find out how to determine which one to use.

Thanks!

Re: Which leg on the tangent?

The angle for which you are evaluating "tan" is between the hypotenuse (i.e. the longest side, opposite the right angle) and the adjacent side.

The adjacent side is (1) adjacent to the angle, and (2) not the hypotenuse.
