Perimeter = 57 57 = x + (x +2) + (x + 4) | Those are the 3 sides of the triangle, I add 2 and 4 to the 2nd and 3rd sides because they're odd numbers, there must be another number between them. 57 = 3x + 6 | That's the equation. 51 = 3x | Solving it 17 = x | This is the value of x, you only have to add 2 and 4 to get the next odd numbers. So the measures of the sides are: 17, 19 and 21
