Question

two equal sides of a triangle are each 5 meters less than twice the third side.if the peremeter of the triangle is 55 meters find the lengths of each side

Answer 1

let the side be x

then

each equal side = 2x-5

perimeter = 55

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

5x= 65

x= 13

side 1 = x = 13m

each equal side = 2x-5 = 21m
