I think you are supposed to divide the sum of the interior angles of the polygon (360 degrees) by the exterior angles of the polygon (72 degrees). When you do this: 360 / 72 = 5 sides.
This would be a pentagon.
12 = 2/3(x - 3)
<em><u>Distributive property.</u></em>
12 = 2/3x - 2
<em><u>Add 2 to both sides.</u></em>
14 = 2/3x
<em><u>Multiply both sides by 3.</u></em>
42 = 2x
<em><u>Divide both sides by 2.</u></em>
21 = x
The value of x is equal to 21.
