Question

Two equal sides of an is osceles triangle are each 9m less than twice the third side if the perimeter of the triangle is 72m find the lengths 0f it's side

Answer 1

Answer:

The sides are 27m, 27m, and 18m

Step-by-step explanation:

Let the third side be x

Therefore, the two equal sides are:

2x-9 and 2x-9

The sum of the sides is 72m

Therefore, 2(2x-9) + x = 72

Thus, 4x-18 +x =72

X = 18

Subtituting the values, we get 18, 27, 27
