If all the interior angles add up to 8280 degrees then (8280+360)/180 = 48 sides
Each interor angle will measure 144 degrees So the 10 interior angles will add up to 1440 degrees
If an interior angle is 40 degrees, the polygon must be irregular since the smallest angle for a regular polygon is 60 degrees. Since it is irregular, the polygon can have any number of sides.
the center angle of any polygon is 360 degrees
150 degrees.
Providing it's a regular polygon:- Each exterior angle 3.6 degrees Each interior angle 176.4 degrees
An equilateral triangle is a polygon that has a measure of 60o for each angle.
The smallest internal angle possible for a regular polygon is 60 degrees. So either the angle is not 12 degrees or it is not an internal angle.
Each interior angle will measure 156 degrees
Each interior angle will measure 162 degrees
Exterior angle: 24 degrees Interior angle: 156 degrees
Exterior angle: 12 degrees Interior angle: 168 degrees
If each interior angle is 175 degrees then the polygon will have 72 sides
