Question

each of two equal sides of a triangle is 5 M less than 7 times the third side find the dimensions of the triangle if its perimeter is 3 X + 26​

Answer 1

hope it helps...........

Answer 2

let the 3rd side be X equal sides = 7x-5 perimeter = x+7x-5+ 7x-5 =15x-10),15x-10=3x+26 ,15x-3x = 26+10, 12x=36 , x=36/12 x= 3 equal sides =7*3-5=21-5=16 third side = 3m
