Question 678229: one side of a triangle is 2 feet more than another side and the third side is 5 feet less than the sum of the other two sides. If the perimeter is 55 feet, what is the length of each side? Answer by ReadingBoosters(3246) (Show Source):
You can put this solution on YOUR website! a = 2 + b
c = (a+b)-5
p = 55
...
55 = a+b+c
55 = (2+b)+b+((2+b)+b)-5
...
55 = 4b - 1
54 = 4b
b = 13.5
...
a = 2 + 13.5 = 15.5
...
c = (15.5+13.5) - 5 = 29-5 = 24
...
Sides are 15.5, 13.5 and 24
