the answer :
A four-sided polygon is a quadrilateral, like a square or a rectangle.
In a quadrilateral, all of the interior angles add up to 360 degrees.
130 + 110 + x - 3 + x = 360 {added all the angles and set equal to 360}
2x + 237 = 360 {combined like terms}
2x = 123 {subtracted 237 from both sides}
x = 61.5 {divided both sides by 2}
