The total number of degrees in any regular polygon is calculated by (S-2) * 180º, where S = the number of sides. So, for a decagon the total is 8 * 180º = 1440º, and the measure of each interior angle is 144º, or 1/10th of the total.
The last bit is correct only if the decagon is regular. It need not be.

How many acute angles in a decagon?
A decagon is a polygon with 10 sides. In a decagon, each interior angle measures 144 degrees. An acute angle is an angle that measures less than 90 degrees. Since all the interior angles of a decagon are 144 degrees, there are no acute angles in a decagon.
How many right angles in a decagon?
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?
