**Debbie**, Tuesday, November 30, 2010 at 9:32amThank you! That was a fast answer! What if it was angles? The angles of a triangles have the ratio 3:4:5 - would you say that 3x + 4x + 5x = 180 and then solve for x?

**drwls**, Tuesday, November 30, 2010 at 9:38amYes, that would give you the angles, once you have solved for x, which is 15 degrees in this case.
