1.1080-( n − 2 ) × 180 ∘ where is the number of sides/All the interior angles in a regular polygon are equal
2.36 -A decagon has 10 sides so its interior angles add up to 180(10) - 360 = 1440 degrees. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees.
3.27 diagonals-n(n - 3)/2; thus, a nonagon has 9(9 - 3)/2 = 9(6)/2 = 54/2 = 27 diagonals.

5.140- (n-2)180 de-gs. n-2 = 5 Add 2 to both sides. n = 7 This is the number of sides in the polygon the sum of whose interior angles is 900 degrees.
