If the sides of a triangle are in the ratio 3:4:5 and the perimeter of the triangle is 72 inches what are the lengths of the sides?
Answered by bobpursley
3x+4x+5x=72
solve for x, then you have it.

Thank 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?
Answered by drwls
Yes, that would give you the angles, once you have solved for x, which is 15 degrees in this case.
