Question

two sides of a triangle are each 5 m less than twice the third side if the perimeter of the triangle is 55 then find the length of its sides

Answer 1

let one side be xm

other 2 sides be 2x - 5m

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

5x - 10 = 55

5x = 55 + 10 = 65

5x = 65

x = 13cm

2x - 5 = 21cm

therefore the three sides are 13cm , 21cm , 21cm
