Question

Find the sum of the measures of exterior angles, one at each vertex, of an octagon.

Answer 1

Answer:

C. 1080

Step-by-step explanation:

1) Find the measure of one interior angle  

2) From that, find the measure of one exterior angle  

3) Multiply that by 8

Answer 2

A rule of polygons is that the sum of the exterior angles always equals 360 degrees, but lets prove this for a regular octagon (8-sides). First we must figure out what eachof the interior angles equal. To do this we use the formula: ((n-2)*180)/n where n is the number of sides of the polygon
