Sum of what aspect of a 20-gon: the length of its sides, its interior angles, its exterior angles, its apothems?
Sum of the angles of a regular polygon = (#sides - 2) * 180. Sum of 20-gon angles = (20-2) * 180 = 3240
Th esum is 3,600 degrees. 3,240 of them are inside the 20-gon, and the other 360 are outside.
3240 degrees
The formula is: (20-2)*180 = 3240 degrees which is the total sum of interior angles
3240. Stick it to Iqity.
The sum of the interior angles add up to 3240 degrees.
The 20 interior angles add up to 3240 degrees
