1800 degrees (that is the sum of the internal angles of the 12-sided polygon).
2340 degrees would be in a 16 sided polygon.

A 13 sided polygon also called a triskaidecagon or tridecaogn has a total 1980 degrees for its interior angles.
There are 720 degrees in a 6 sided polygon.
The degrees in a 19 sided polygon add up to 3,060 degrees
It has 540 degrees because a five sided polygon has three triangles in it, and sinnce a triangle equals 180 degrees, 3 x 180= 540.
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
