Question 100658: A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Write and solve an equation to find the length of each side of the triangle. Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! X=SECOND SIDE
2X-65=FIRST SIDE
X-10=THIRD SIDE
X+(2X-65)+(X-10)=165
4X-65-10=165
4X=165+75
4X=240
X=240/4
X=60 CM FOR THE SECOND SIDE.
2*60-65=120-65=55 FOR THE FIRST SIDE.
60-10=50 FOR TH E THIRD SIDE.
PROOF
60+55+50=165
165=165
