Question

two sides of a triangle have the same length the third side measures 6 in less than twice that length the perimeter of the triangle is 22m find the length of the three sides

Answer 1

side1: x

side2: x

side3: 2x - 6

Perimeter (P) = side1 + side2 + side3

22 = x + x + 2x - 6

28 = 4x

7 = x

side2: 2x - 6 = 2(7) - 6 = 14 - 8 = 8

Answer: 7, 7, 8
