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.

A regular 10 sided decagon has 10 exterior acute angles each measuring 36 degrees

It has no interior acute angles because each interior angle measure 144 degrees

What is the maximum number of vertex angles on an irregular decagon that can be acute?

Take a star for example, the points are acute angles, so, there would be five. * * * * * Taking a star, for example, does not give the maximum because the maximum is likely to appear in an unusual shape. It should be possible to have a decagon with 7 acute angles and 3 reflex angles.
