The sum of the interior angle measures of a 13-gon?

Answer 1

The sum of the interior angle measures of a polygon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a 13-gon, this would be ( (13 - 2) \times 180^\circ = 11 \times 180^\circ = 1980^\circ ). Therefore, the sum of the interior angle measures of a 13-gon is 1980 degrees.
