How long is each side of the triangle?

Question

The first side of a triangle is 2 inches shorter than the second side. The third side is 5 inches longer than the second. If the perimeter of the triangle is 33 inches, how long is each side?

Answer 1

s=second side

s-2=first side

s+5=third side

s+s-2+s+5=33

3s+3=33

3s=30

s=10 inches

s-2=8 inches

s+5=15 inches
