Respuesta :
In a regular 13 sided polygon you would calculate the interior angles with (n-2)180 N is the number of sides so subtract 13-2 to get 11 then multiply 11 times 180 to get 1,980
The sum of the interior angle measures of a 13-gon is 1980°.
The sum of the interior angle measures of a shape is given as:
= (n - 2) × 180
Therefore, since this is a 13-gon, it'll be:
= (n - 2) × 180
= (13 - 2) × 180
= 11 × 180
= 1980
Therefore, the sum of the interior angle measures of a 13-gon is 1980°
