A decagon has 10 sides and so 2*10 = 20
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 is a polygon with 10 sides and 10 angles. Each angle in a regular decagon measures 144 degrees. The sum of the interior angles of a decagon is 1440 degrees. Decagons have lines of symmetry that pass through the center of the shape and divide it into two equal halves.
