The second side of a triangle is 8 inches less than the first side. The third side is 14 inches more than the first side. The perimeter of the triangle is 63 inches. Find each side of the triangle.

Answer 1

s = f-8, t =14+f

f+s+t = 63

f + f-8 + 14+f = 63

3f = 63 -6 = 57

f = 57/3 = 19 = first side

s = 11 = second side

t = 33 = third side

19+11+33 = 63
