The sum of the interior angles of a triangle is 180 deg.
For a convex polygon with n sides we can divide it to n-2 triangles.
So the answer, if the polygon is convex, is (13-2)*180= 1980 deg

The polygon need not be convex. The formula for the sum of the interior angles is valid as long as the polygon is simple - that it, its sides do not cross each other inside the polygon.

What is the total interior angle sum of a polygon?
(number of sides -2)*180 = sum of interior angles
What is the sum of the interior angle measures of a 25 - sided polygon?
The method of finding the sum of the interior angles of a polygon is by multiplying the (number of sides)-2 by 180, so the sum of the interior angle measures in a 25-sided polygon would be 23*180, or 4140 degrees.
