Depends on if you mean interior or exterior angle. The sum of the exterior is 360 no matter how many sides there are so each exterior angle is 360/12. The sum of the interiors is (12-2)180=1800 so each angle is 1800/12

The measure of one exterior angle of a regular 18-gon is 20°. The sum of all exterior angles of a regular polygon is always 360° so the measure of each exterior angle can be calculated by dividing 360° by the number of sides. In this case that would be: 360° 18 = 20°Therefore the measure of one exterior angle of a regular 18-gon is 20°.
Each interior angle is 165 degrees
18 degrees providing it is a regular polygon
It is 2340/15 = 156 degrees
It's 7/8 of 180 = 157.5 degrees
