There are 1440 degrees in a decagon.
1440
all decagons have 1440 degrees
A decagon is a 10 sided polygon. Exterior degrees total 360 Interior degrees total 1440
The angles of any triangle add to 180 degrees. Whether or not the triangle is in a decagon is totally irrelevant.

A decagon will always have its interior angles measure 1480
There are 8 triangles inside a 10 sided decagon
A decagon is ten sided. The total of all the angles inside the corners of an n-sided polygon is (n-2)x180 degrees. So for 10 sides this is 8x180=1440 degrees. The polygon does not even have to have equal sides.

A decagon is a 10 sided polygon. Exterior degrees total 360 Interior degrees total 1440
Each interior angle of a regular decagon would measure 144 degrees,
The angles of any triangle add to 180 degrees. Whether or not the triangle is in a decagon is totally irrelevant.
Exterior degrees 360 Interior degrees 1440
The sum of the interior angles of a dodecagon (not duo-decagon) is (12 - 2)*180 = 1800 degrees.
Interior angle: 144 degrees
