180 x 9 = 1620
1620 The easiest way to do this in your head is multiply 180 by 10 i.e. you add a "0" on the end so 1800, and then subtract 180 to give you 9 multiples of 180: 1800-180 = 1620

180*(11-2) = 180*9 = 1620 degrees.

To find the number of sides ( n ) in a polygon given the sum of its interior angles, you can use the formula ( S = (n - 2) \times 180 ), where ( S ) is the sum of the interior angles. Setting ( S = 1620 ), we get: [ 1620 = (n - 2) \times 180 ] Solving for ( n ): [ n - 2 = \frac{1620}{180} = 9 \ n = 11 ] Thus, the polygon has 11 sides.
