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.

A dodecagon is a 12 sided shape that has 12 interior angles that add up to 1800 degrees and 12 exterior angles that add up to 360 degrees
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
Well hello there, friend! A 12-sided polygon is called a dodecagon. To find the sum of the interior angles in any polygon, you can use the formula (n-2) x 180 degrees, where n is the number of sides. So, for a dodecagon, the sum of the interior angles would be (12-2) x 180 = 1800 degrees. Each interior angle in a dodecagon would be 1800 degrees divided by 12, which equals 150 degrees.

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
The 3D shape that has 12 faces is called a dodecahedron. It is a polyhedron with 12 regular pentagonal faces. Each face of a dodecahedron is a regular polygon with five sides of equal length and five equal interior angles.
