How many degrees are in a dodecagon?
The interior angles of a dodecagon add up to 1800 degrees.
The measure of an interior angle of a regular polygon is 150 degrees Find the number of sides?
AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon
What is the sum of the interior angles of an dodecagon?
1800 degrees from 12 angels
What is the sum of the measures of the interior angles of a dodecagon?
The sum of the interior angles of an n-sided polygon is (n-2)x180. For a dodecagon n=12, so the sum of the interior angles is: (12-2)x180o = 10 x 180 degrees = 1800 degrees
What is the sum of the interior angles in a dodecagon?
180*(12-2) = 180*10 = 1800 degrees.
