Can a non-equilateral triangle with integer sides and integer angles (in degrees) exist?

I'm wondering if a triangle with integer sides and integer angles in degrees exists, which is not equilateral. Could someone come up with a proof for why or why not? *Edit:* Please do not answer with a triangle which has integer sides only. The triangle must have integer angles in degrees; this means they must actually be integers, not rounded off.

P.S. If you find any other angle that sine has a rational value for that angle (I don't think there are any), see if it is possible to make a triangle with those angles.
