For a regular 12-sided polygon what is the measure of an exterior angle

Just divide 360 by 12.

Then, you look for the interior angle, which is $180 - \frac{360}{12}$

Now that you have this, subtract this from 360 degrees.

Exterior angle = $360 - (180 - \frac{360}{12}) = 360 - 180 + \frac{360}{12} = 180 - \frac{360}{12}$
