Improved Answer:-

33 because 1/2*(332-99) = 495

Answer 2

To find the number of sides in a polygon given the number of diagonals, you can use the formula: (d = \frac{n(n-3)}{2}), where (d) is the number of diagonals and (n) is the number of sides. In this case, you have 495 diagonals, so you can set up the equation as (495 = \frac{n(n-3)}{2}) and solve for (n). By rearranging the equation and factoring, you can find that the polygon has 22 sides.
