Geometry question

[Kelemvor]

OK, This has nothing to do with school but I haven't done this in years.

If I have a right triangle and I know the lengths of all the sides, how do I figure out the angles or the two non-90 angles? I need to cut some plywood and want to set my gauge to the right angle to make sure it comes out right. What's the equation to do that?

The dimentions I'm working with are:
A=10
B=22
c=Sqrt(10^2 + 22^2) = 24.16

Just need to figure out the angles.

If the link that Electric Amish gave didn't help then here are the answers.

We'll say that the B lengthis on the bottom and the A length is the one that is the vertical side.

The top angle is 65.55 degrees
The angle on the length along the B angle is 24.45.

Only have to work out one angle as all angles in a right angle triangle = 180.

Glad to help as I'll sure as hell be getting maths help from here!
