I am going to assume that you mean a regular octagon.
If you use the formula 180(n-2), where n=the number of sides, plug in 8 for an octagon and you get 1080 as the sum of the interior angles. Now divide this by 8 in order to get the measure of one of the interior angles, which turns out to be 135.
Now, if you are looking for the exterior angle measurement, then simply subtract 135 from 180 to get 45.
45 is your exterior angle measurement, 135 is your interior angle measurement.
