Find the measrue of an angle in each polygon if the polygon is regular. Round to the nearest tenth of a degree if necessary.
-----
The sum of the exterior for all polygons is 360 degrees
Divide 360 by the # of sides.
The interior angle = 180 - exterior
---------------
1. dodecagon (12-sided)
2. 14-gon
3. 18-gon
4. 36-gon
