A polygon is any figure sided with three sides and above such that triangle (3) is the smallest polygon. A nonagon is a polygon with 9 sides. To get the sum of interior angles of a polygon we use the formula;
(n-2) 180 or (n-4)90 where n is the number of sides.
Therefore, for a nonagon the sum of interior angles = (9-2) 180 = 1260 degrees
If we add all the angles we should get 1260, considering the remaining angles to be each x
Thus 138+154 +145 +132 +128 +147 +130 + x +x =1260
= 974 + 2x = 1260
= 2x = 286
= 143
therefore, each of the other angles was 143

4b - k = 7b + 3
None of the answers are true, a b are always b minus.</span>
The answer to your question is 12b^2
