Question

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

Answer 1

Step-by-step explanation:

This is very simple you just have to let third side x.

Answer 2

Answer:

Let the third side be X

Therefore the other 2 sides = 2x-5

Perimeter = 55 m

According to the question

X+2x-5+2x-5 =55

5x -10 = 55

5x = 45

x = 45÷5

X= 9

The third side= 9m

First and second side = (2×9)-5

=13m
