Each exterior angle measures 30 degrees
Exterior angle 12 degrees Interior angle 168 degrees
Each exterior angle = 360/12 = 30 degrees. Each interior angle = 180 - 30 =150 degrees.
Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)
Providing that it is a regular duodecagon each exterior angle measures 30 degrees
A regular polygon of 30 sides will each have an exterior angle of 12 degrees and an interior angle of 168 degrees.
If its a regular polgon and each exterior angle is 30 degrees then it will have 360/30 = 12 sides
150 degrees.
Exterior Sum: 180 180 degrees / 6 angles= 30 degrees per exterior angle. (I'm pretty sure! Double check this!)
If each exterior angle is 30 degrees the polygon has 360/30 = 12 sides.
Exterior angle: 12 degrees Interior angle: 168 degrees
Providing that it's a regular polygon then each exterior angle will measure 12 degrees.
