Question

The perimeter of an isosceles triangle is 50 cm. If the congruent sides of the triangle are each twice as long as the remaining side, what is the length of each side of the triangle?

Answer 1

x=10cm

Explanation:

congruent sides are each (2x + 2x) remaining side (x)

2x+2x+x = 5x

5x=50cm

50÷5=10

x=10cm
