Mark this as the brainliest answer...

Step-by-step explanation:

each interior angle of the regular octagon is equal to 135 degrees. Each exterior angle is the supplementary angle to the interior angle at the vertex of the polygon, so in this case each exterior angle is equal to 45 degrees. (180 - 135 = 45). Remember that supplementary angles add up to 180 degrees.

Answer 2

the formula of finding the sum of the angles in octagon is

n - 2 x 180

n = no of the sides in the polygon

no of sides in a octogon = 8

8 -2 x 180

6 * 180

1080 degrees
