1800 degrees (that is the sum of the internal angles of the 12-sided polygon).
The sum of the exterior angles of a polygon, however many sides it has, is 360 degrees. If the 20 sided polygon is regular, its angles are equal, and each is then 360/20 = 18 degrees.
2340 degrees would be in a 16 sided polygon.

There are 720 degrees in a 6 sided polygon.
1,440 Degrees
The degrees in a 19 sided polygon add up to 3,060 degrees
The interior angles of a fifteen sided polygon amount to 2340 degrees.
The interior angles of a 13 sided polygon add up to 1980 degrees
1800 degrees (that is the sum of the internal angles of the 12-sided polygon).

2340 degrees would be in a 16 sided polygon.
if it is a polygon then the total interior angles will equal 1080. so ear angle will be 135 degrees.
