The longest side of the triangle is 3 in longer than the shortest side. The medium side is 2 in longer than the shortest side. If the perimeter of the triangle is 20 in., what are the lengths of the three sides?
---
Let shortest side be "x".
Medium side = "x+2"
Longest side = "x+3"
----
Equation:
x + x+2 + x+3 = 20
3x+5 = 20
3x =15
x = 5 in (shortest side)
x+2 = 7 in (midium side)
x+3 = 8 in (largest side)
