Hint: In a regular polygon the sides are all the same length and the interior angles are all the same size.
In a regular polygon, the exterior angle = 360n , n is the number of side
The regular octagon is a polygon with 8 Equal sides.
Substitute n=8 into the formula 360n.

Complete step-by-step answer:
In the regular: All sides equal and all angles equal.
The sum of the exterior angles of a polygon is 360
The size of exterior angle = 360n , n is the number of sides.
The number of sides of the octagon is 8.
Substitute n=8 into 360n.
The size of exterior angle = 3608
Each exterior angle =45
In the regular, all angles are equal so the size of each angle is 45.

Final Answer: The size of each exterior angle of a regular octagon.

Note:
The list of some common formula;
Interior Angle = 180 – Exterior Angle
Exterior Angle = 180 – Interior Angle
The interior angle =(n2)n × 180
The exterior angle = 360n , n is the number of side
