In an isosceles triangle, 2 sides of equal length are together 8 cm longer than the third side. If the perimeter of the triangle is 32 cm, what is the length of each side?
Please show any working out!
Call x the length of one of the two equal sides
Call y the length of the third side
because perimeter = length of all three sides added together
because "2 sides of equal length are together 8cm longer than third side"
One way to solve is by substitution
So each of the equal sides has length ten
