_______________________________
♦ As we all know that sum of Exterior angles of polygon is 360°
♦Since it has 8 sides , so it is an octagon.
♦ As, it is a regular octagon, so each of the interior angles of octagon are equal.
Now,
♦ This means that each interior angle of the regular octagon is equal to degrees.
♦ Each exterior angle is the supplementary angle to the interior angle at the vertex of the polygon.
•°• Each exterior angle = (180 - 135) = 45°.
Therefore, each exterior angle of a regular polygon with 8 sides is .

Answer:
45°
Step-by-step explanation:
1. (n-2) x 180°
n°
2. = (8-2) x 180°
8
3. = 6 x 180°
8
4. = 1080°
8
5. = 135°
6. Each exterior angle is supplementary, so (180° - 135°) = 45°
7. ∴ Each exterior angle is 45°.
