The sum of the angles of any polygon with 'n' sides is (n - 2) times 180 degrees.1980 / 180 = 11 , so the polygon has 13 sides and 13 angles.If the polygon is regular, then all the angles are equal.Each interior angle is 1980/13 = 152.308 degrees (rounded
Since a and b are both greater than zero and are real numbers, they are both positive. The only quadrant that can contain a point with positive values for both x and y is Quadrant 1.
