Answer:
4320 degrees
Step-by-step explanation:
If interior angles are 3960 degrees then there are 24 sides. If polygon is regular, size of each exterior angle is 15 degrees.
A polygon has as many pairs of interior and exterior as number of its sides. Further each pair of exterior and interior add up to
180 degrees.
Sum of all the exterior angles of any polygon is
360 degrees
As sum of all the interior angles of the polygon is
3960 degrees
Sum of all pairs of exterior and interior angles is
3960 degrees + 360degrees = 4320 degrees
