 Question 26213: okay... welcome to my nightmear! The perimeter of a triangle is 33 centimeters. The first side is 5 cetimeters shorter than the second, and the third is twice the first. Find the lengths of the sides... I have a hard new class that I just entered and I'm not caught up yet. I've gotten as much help as I could, and this problem is the basis of the rest of my homework so if I could get this answer than I could probably figure the rest out. If you could show me the steps of the problem so that I can follow it... I would be eternally greatfull! thank you :-pAnswer by longjonsilver(2297)   (Show Source): You can put this solution on YOUR website!easy :-) Let second side be x then first is x-5 and third is 2(x-5) perimeter is (x-5) + x + 2(x-5) = 33 --> x - 5 + x + 2x - 10 = 33 4x - 15 = 33 4x = 48 x = 48/4 x = 12cm So, first side is 7cm second is 12cm third is 14cm -->check: these 3 add to give? 33cm, the perimeter, so correct! jon.
