What is the measure of one angle on a regular 12 sided polygon?

The formula to calculate the TOTAL degrees of all angles in a shape is to use the formula
(N-2) x 180 where N is the number of sides of that shape.
So in this case:
(12 - 2) x 180
10 x 180 = 1800o
This means there is a total of 1800o in a 12 sided shape.
Now since we know it's a regular shape, this means every angle making up this 12 sided shape will be the same. So this means we can divide the total number of degrees by 12. So:
1800 / 12 = 150o is the size of one angle.
I hope that helps.

What is the measure of a central angle of a regular ten sided polygon?
the center angle of any polygon is 360 degrees
How do you calculate the measure of a central angle of a regular nine sided polygon?
To calculate the measure of a central angle of a regular nine-sided polygon, divide 360 degrees by the number of sides. In this case, divide 360 by 9. The measure of the central angle of a regular nine-sided polygon is 40 degrees.
What is the angle measure of a 50 sided polygon?
The interior angle of a regular polygon with x sides is 180(x-2)/x. As a result, each angle of a regular 50-sided polygon is 172.8. The exterior angles are 7.2
