The sum of the exterior angles of a polygon is 360o. For a dodecagon (12 sides) the exterior angle is 360o / 12 = 30o.
The interior and exterior angles are supplementary and so they sum to 180o; thus the interior angle of a dodecagon is 180o - 30o = 150o.
For an interior angle of 144o, the exterior angle is 180o - 144o = 36o, so there are 360o / 36o = 10 sides (a decagon).
If your "53" is in degrees, then the vertex angle is 74 degrees.
80 degrees.
If each angle measures 90 degrees the polygon is a square and so its angles sum to 360 degrees.
Providing that it is a regular nonagon then each exterior angle measures 40 degrees and each interior angle measures 140 degrees
It is: 180-72 = 108 degrees and it is a regular 5 sided pentagon
If your "53" is in degrees, then the vertex angle is 74 degrees.
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
Vertex angle = 180 - 2(62) = 56 degrees
90 degrees
57.5 degrees
Vertex angle is 180-53-53 = 74 degrees
80 degrees.
