Hlw dude !

QUESTION :-

Two equal side of an isosceles triangle are each 9m less than twice the third side. If the perimeter of the triangle is 72 find the length of its side. ​

ANSWER :-

Given :

Perimeter = 72 m.

Solution :

Let it's third side be 'x'.

According to the given condition,

Each of its equal side = 2x - 9 m.

Then,

x + 2x - 9 + 2x - 9 = 72 m.

5x - 18 = 72 m

5x = 90 m.

x = 90/5 m.

x = 18 m.

Then length of its equal sides = 2x - 9

2x - 9 = 2 x 18 - 9.

27 m.

It's third side = 18 m.

Checking :

It is already given that perimeter is 72 m.

According to the given condition,

2x - 9 + 2x - 9 + x = 72 m

27 m + 27 m + 18 m = 72 m.

Hope it helps!!
