The equation for and interior angle of an n sided shape is (n-2)180/n
In this case we have a 12 sided shape. Plugging n=12 into the equation gives us:
(12-2)180/12
= 10x180/12
= 150
Thus an interior angle of a 12 sided shape would be 150 degrees.

What is the sum of the measure of the interior angles of a 12-sided polygon?
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
Interior and exterior angles of a 30 sided polygon?
The total of the interior angles equal 5040, and each angle measures 168 degrees The total of the exterior angles equal 360, and each angle measures 12 degrees
What are the angles of a 12 sided polygon?
to calculate this, you must find out how many triangles you can draw in to the shape. do this by picking an angle. draw a line to all of the other angles. (for a 12 sided, there would be 9, subtract 3 from any shape to see.) mutiply the number of triangles by 180 degrees. this should be the degrees of the shape. for a 12 sider, the answer would be 1620 degrees.
What is the exterior and interior angle of a shape with 12 sides?
If this shape is a regular 12-sided polygon, then the sum of its angles is 1,800 degrees [(n -2)180]. So the measure of one angle is 150 degrees (1,800/12), and the exterior angle is 30 degrees (180 - 150).
