the measure of an interior angle or a regular polygon is given.
Find the measure or find the number of side in each polygon if it is 168.
---
If the interior angle is 168, the corresponding exterior angle is 12.
---
Rule: The sum of ALL of the exterior angles is 360.
---
So, # of exterior angles is 360/12 = 30
---
Therefore # of sides is 30
