It has 11. There are the 10 sides (decagonal) and then the base. So 11 total.
A pyramid has one more corner and faces than the number of sides in its base; thus a decagonal pyramid has 10 + 1 = 11 faces and corners. A pyramid has twice as many edges as sides in its base; thus a decagonal pyramid has 2 X 10 = 20 edges.
It depends on a decagonal what. A decagonal prism has 20 vertices. A decagonal pyramid has 11 vertices.
The question cannot be answered because it makes no sense. "Decagonal" is an adjective, not a noun and the answer will depend on whether the question is about a decagonal pyramid, a decagonal prism or decagonal bipyramid, or something else.

20 faces and 10 sides
A decagonal prism has 12 faces.
No. 11 sides.
There is no such word as "deconagnol". If you meant decagonal, then the answer is 12 faces. If you did not mean decagonal then please resubmit using corrected spelling.

There are 30 edges on a decagonal prism.

A star has 10 sides and 5 vertices but if it's a decagonal star then 20 sides (10 for the star and 10 for the star) and 10 vertices (for the decagon in the middle, hence decagonal star). But, if it's pentagram star then 10 sides and 10 vertices.
A decagonal prism has 20 vertices: 10 at each end.
