Question

Two equal sides of a triangle are each 5 mless then twice the third side. if the perimeter of the triangleis 55 m,find the length of its sides

Answer 1

let the length of the equal side be x and the length of the third side be y then from data given in the question

x + 5 = 2y and 2x + y = 55

solving the equations we get x = 21 and y = 13

so the dimensions of the triangle are 21, 21, 13
