What are the measures of the exterior angles of a regular octagon? A. 24 B. 60 C. 8 D. 45
The answer is D. Remember that all exterior angles of a regular figure add to 360 degrees? Well, all you have to do here, is find what number, when multiplied 8 times, will equal 360. When you do 45 x 8, the answer is, indeed 360.
You're very welcome! :)
