The sum of angles in a decagon [10 sided polygon] is 1440°. There cannot be 8 or more reflex angles, since 8 x 180° = 1440°. So see if 7 will work.
You could have 7 angles at 181°, then 3 angles, which add up to 173° {say 58°, 58° & 57°}, and it would be a valid decagon.
A decagon has 10 sides. It also have 10 angles.

It has 10 interior angles that add up to 1440 degrees
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.

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.
It has 10 interior angles that add up to 1440 degrees
