All triangles have angles that add up to 180 degrees. You know that one angle is 90 degrees (since it's a right triangle). If you do not know another angle, you will have to do a little work.
If you do, all you have to do is subtract 90 and the other known angle from 180. That will give you the remaining angle.
If you don't...

Good luck!

Let a, b, c be the sides of a right triangle.
Let x, y, z be the angles, with z the right ange.
sin x = a/c
cos x = b/c
tan x = a/b
These ratios have one and only one angle.
