12 exterior angles that add up to 360 degrees 12 interior angles that add up to 1800 degrees
where n = number of sides total sum of interior angles: (n - 2) * 180 so (12-2)*180 then divide that number by n 10*180 / 12
The sum of the exterior angles of any polygon is 360 degrees. So for a regular dodecagon (12-gon), each exterior angle is 360/12 = 30 degrees. And so, each interior angle is 180 - 30 = 150 degrees.
90 x ((2 x 12) - 4) degrees ie 1800o
The interior angles of a 12 sided polygon add up to: (12-2)*180 = 1800 degrees
1800 degrees
Measures of what? The interior angles, the exterior angles, the lengths of sides?
The interior angles of a 12-gon add up to 1800 degees
The sum of the interior angles is 1,800 degrees for any 12-agon,no matter how it's shaped.
The sum of exterior angles for any figure is 360. If you want the sum of the interior angles use the equation 180(n-2) for n equals number of sides.
Its interior angles add up to 1800 degrees and its exterior angles add up to 360 degrees
12
The sum of the interior angles of an n-gon is (n-2)*180 degrees So for n = 14, the sum is 12*180 = 2160 So each of the 14 angles is 2160/14 = 154.285714... degrees
where n = number of sides total sum of interior angles: (n - 2) * 180 so (12-2)*180
180 degrees( 12-2)=1800degrees This is the sum of the interior angles. So divide 1800 by 12 and have the measure of each angle.
The sum of the interior angles of a n-gon is (n-2)*180 So, (n-2)*180 = 1800 ie n-2 = 10 so that n = 12 It is a 12 sided polygon or dodecagon.
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
