The central angle in any closed shape must be 360 degrees. This is the measure of the angles about a point.

It depends on whether or not the decagon is a perfect decagon or a complex decagon. However, a perfect decagon has no acute angles.
A decagon has ten vertices.
There (not their) are 10 angles.
A decagon has 10 sides. It also have 10 angles.
A decagon will always have its interior angles measure 1480
None.

A decagon can have acute angles.
Oh, dude, a decagon has 10 sides, right? So, each angle in a regular decagon measures 144 degrees. Now, a right angle is 90 degrees, so technically, there are zero right angles in a decagon. But hey, who's counting, right?
The sum of the interior angles of a dodecagon (not duo-decagon) is (12 - 2)*180 = 1800 degrees.
