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
all decagons have 1440 degrees
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
The interior angles of a decagon add uo to 1440 degrees
Each interior angle of a regular decagon is 144 degrees
