Question

two equal sides of a triangle are each 5 meters less than twice the
third side. if the perimeter of triangle is 55 meters find the langit of its sides​

Answer 1

Answer:

Let the length of third side be x.

Then, length of two equal sides will be = 2x - 5

Perimeter = 2x - 5 + 2x - 5 + x

or, 55 = 5x -10

or, 5x = 65

or, x = 13

So sides of the triangle are 13, 21 and 21
