In what type of regular polygon is each interior angle equal to 168°?
Answer provided by our tutors
If the interior angle is 168o then the exterior angle is 180o - 168o = 12o.
The sum of the exterior angles is 360o, so if each one is 12o, there are 360o ÷ 12o = 30; so there must be 30 sides.
A regular polygon with 30 sides has each interior angle of 168o.
