Question

if the base of isosceles triangle exceeds one of the equal side by 10cm and and perimeter is 70 cm then equal side of triangle is

Answer 1

Let the equal sides of isosceles tri angle be x cm

so base = x + 10 cm

so by the condition given in your question we get equation

x + x + x + 10 = 70

3x + 10 = 70

3x = 60

x = 60/3

x = 20

so equal sides of isosceles tri angle is 20 cm
