The 13 interior angles add up to 1980 degrees
The 13 interior angles of a 13 sided polygon add up to 1,980 degrees
1980 degrees
13 * (180 - 360/13) = 1980 degrees
The sum of the interior angles is (15-2)*180 = 13*180 = 2340 degrees
find the sum of the measures of the interior angles of 13-gon.
Its 13 interior angles add up to 1980 degrees
The 13 interior angles add up to 1980 degrees
The 13 interior angles of a 13 sided polygon add up to 1,980 degrees
It is: (13-2)*180 = 1980 degrees
1980 degrees
13 * (180 - 360/13) = 1980 degrees
13 sides
Sum of exterior angles = 360 degrees Sum of interior angles = 1980 degrees
The sum of the interior angles is (15-2)*180 = 13*180 = 2340 degrees
Exterior angles add up to 360 degrees Interior angles add up to 1980 degrees
A 13 sided polygon interior angles add up to 1980 degrees
