12,600 degrees -- and it doesn't matter whether the 72-gon is regular or not.
The sum of the exterior angles (from an extension of each side to the next) of any polygon is always 360 degrees. Therefore the sum of the interior angles is always (number of sides) * 180 - 360. 72 * 180 - 360 = 70 * 180 = 12,600.
Interior angles of a 45-gon add up to 7740 degrees Each interior angle of a regular 45-gon measures 172 degrees
Each interior angle measures 177.12 degrees
Measures of what? The interior angles, the exterior angles, the lengths of sides?
12,600
Each interior angle of a regular 45-gon measures 172 degrees
Each interior angle measures 140 degrees.
Interior angles of a 45-gon add up to 7740 degrees Each interior angle of a regular 45-gon measures 172 degrees
Each interior angle measures 177.12 degrees
Each interior angles measures 150 degrees
the sum of the interior angles of a 35-gon.
Exterior angle measures 18 degrees Interior angle measures 162 degrees
Interior angles of a regular 18 gon (octdecagon) are 160o.
The interior angles of an 11-gon add up to 1620 degrees
Sum of the angles of a regular polygon = (#sides - 2) * 180. Sum of 20-gon angles = (20-2) * 180 = 3240
find the sum of the measures of the interior angles of 13-gon.
Measures of what? The interior angles, the exterior angles, the lengths of sides?
Providing that it's a regular polygon then each interior angle measures 156 degrees
