Step1: Recall sum of exterior angles

The sum of the exterior angles of any polygon is always $360^{\circ}$.

Step2: Note number of exterior angles

An octagon has 8 exterior angles, and in a regular octagon all exterior angles are equal.

Step3: Calculate measure of angle n

$n=\frac{360^{\circ}}{8}=45^{\circ}$

Answer:

$45^{\circ}$
