Question

Determine the measure of an interior angle of the named regular polygon. If a side of the polygon is extended, determine the supplementary angle of an interior angle. A 24-sided polygon.

Answer 1

S = (n - 1)180

S = (24 - 1)180

Each angle is S / 24, Can you determine?

The sum of exterior angles is always 360º

Each exterior and angle is 360º / 24.
