It doesn't matter whether it's convex or not. The sum of the interior angles of any 13-sided polygon is (11 x 180°) = 1,980°.

The sum of the measures of the interior angles of a convex 13-gon is calculated using the formula (n - 2) × 180°, resulting in 1980 degrees. ;

The sum of the measures of the interior angles of a convex 13-gon is 1980°. This is calculated using the formula ( n − 2 ) × 18 0 ∘ , where n is the number of sides. For a 13-gon, this gives us 11 × 18 0 ∘ = 198 0 ∘ .
