What is the angle of rotation of this regular octagon? what is the measure of an interior angle? a. 45°, 135° b. 22.5°, 135° c. 45°, 108° d. 22.5°, 108°

Option: A is the correct answer.

                  A. 45°,135°

We know that for a regular polygon with n sides the measure of each of the exterior angle is given by:

Also, the measure of each of the interior angles of the regular polygon with n sides is given by:

Here we have n=8 (octagon)

Hence, the measure of each of the exterior angles is:

and measure of each of the interior angles is given by:

                   Hence,

          Measure of interior angle= 135°

       and measure of exterior angle= 45°

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p

nope lol
