Question

Two equal sides of a triangle are each 5 metres less than twice the third side if the perimeter of the triangle is 55 metres find the length of its sides

Answer 1

Step-by-step explanation:

let the 3rd side be x

let the equal side be 2x-5

now;

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

25, 3x-10=55

3x=45

x=15

so length of its sides are 15,25,25
