Question 1023593: The base of an isosceles triangle is 3cm less than the length of the equal sides. If the perimeter of the triangle is 36cn, find the length of each of the sides. Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Hi there,
Make the equal sides = 'x' each
The base = x - 3
Perimeter = two equal sides + base
36cm = x + x + (x - 3)
Collect like terms:
x + x + (x - 3) = 36
x + x + x - 3 = 36
3x = 36 + 3
3x = 39
x = 13
Two equal sides = 13cm each
Base = 10cm.
Hope this helps :-)
