1440 degrees, and every internal angle is 144 degrees
Providing that it is a regular 10 sided decagon then each interior angle is 144 degrees
Any angle that you like. There are no constraints on a single angle of a decagon, only on their sum.
36 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.
