Question

In an Isosceles triangle, the measure of the length of one side is 87 less than 4 times the length of the equal sides. If the perimeter of the triangle is 63 cm, find the sides of the triangle.

Answer 1

Let one of the equal sides be x
Third side = 4x-87
A/Q  2x+4x-87 = 63
6x = 150
x = 25
Equal sides = 25
Third side = 4x-87 = 100-87 = 13cm

Answer 2

Step-by-step explanation:

6x =one side

6x =87+63

6x=150

x=150 upon 6

x=25
