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?

bobpursley,
3x+4x+5x=72
solve for x, then you have it.

Debbie,
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?

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

Debbie,
Thank you so much!
