All eight of the octagon's inside angles add up to 1,080 degrees.
If it's a regular octagon, then each inside angle is 135 degrees.
It doesn't matter if the perimeter is 64 picometers or 64 light years.
The measure of the exterior angle of a convex octagon is indeterminate.
Providing that it is a regular octagon each interior angle measures 135 degrees
45 degree
Each interior angle of a regular 8 sided octagon measures 135 degrees
Any measure that you like. There are no restrictions on an angle of an octagon, only on their sum.
A regular octagon has a sum of 1080 degrees for all angles, 1080 degrees divided by 8 angles is 135 degrees per angle. The perimeter is 200 centimeters divided by 8 sides is 25 centimeters.
An interior angle of a regular octagon is 45 degrees. The exterior angles measure 315 degrees.
The measure of the exterior angle of a convex octagon is indeterminate.
