Question

find the measure of each exterior angle of a regular polygon of 8 sides.

Answer 1

Answer:

A rule of polygons is that the sum of the exterior angles always equals 360 degrees.

Since it is a regular octagon(polygon with 8 sides), so each of the interior angles of octagon are equal.

⇒360/8 = 45 degrees.

Answer 2

Answer:

exterior angle=45

Step-by-step explanation:

each interior angle =(n-2)180/n

=(8-2)180/8

=6*180/8

=1080/8

=135

interior angle+exterior angle=180

135+exterior angle=180

exterior angle=180-135

exterior angle=45
