Measure it. There is no formula for an exterior angle unless you have a regular (or equiangular) polygon. And there is no evidence to suggest that that is the case.
It is: 180-interior angle = exterior angle
With a regular polygon: 360/exterior angle = number of sides
To find the interior angle of a polygon when you know the exterior angle, you can use the relationship that the interior and exterior angles are supplementary. This means they add up to 180 degrees. Therefore, you can calculate the interior angle by subtracting the exterior angle from 180 degrees: Interior Angle = 180° - Exterior Angle.
Interior and adjacent exterior angles form a straight line so exterior angle = 180 - interior angle. If you are satisfied with this reply please consider awarding a Recommended Point to the responder.
The sum of the exterior angles in any polygon is 360 degrees. A nonagon has 9 sides, so to work out a single exterior angle, we divide 360 by 9, which is 40.
It is: 180-interior angle = exterior angle
You cannot. An exterior angle of a decagon can have any value.

If the polygon has n sides (or vertices) each exterior angle is 360/n. Each interior angle = 180 - exterior angle = 180 - 360/n
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle

Each exterior angle 45 degrees Each interior angle 135 degrees
the hypotenuse is the exterior angle
