There are 2 obtuse angles (greater than 90°) : the top and bottom of the X.

It has two obtuse angles
A trapezium has one or two obtuse angles.
An obtuse triangle can have no right angles, and has two equal angles.
A regular octagon has 8 interior obtuse angles.

None... All 4 angles are right angles (right angle means 90 degrees), meaning the angles are neither obtuse, nor acute.
The 4 interior angles of a trapezium add up to 360 degrees and if it's an isosceles trapezium it can have 2 equal obtuse angles and 2 equal acute angles

MATHEMATICS
An obtuse angle is only one angle, however if you meant 'how many degrees?' then an obtuse angle contains more than 90 and less than 180 degrees..
In geometry, angles are created by the intersection of lines or of line segments. A curve is not an angle, and a semi-circle (or complete circle) consists only of one continuous curve. There are no angles as such. If you like, you can conceive of a curve as a collection of infinitely many angles. But you can never see them individually, they are only seen as a group. They are not obtuse (or acute) angles in the normal sense of the term.
All angles are made up when two lines or sides vertexes or intersection points, I think.
It's a Reflex Angle. Many would think that it is obtuse, but obtuse angles go from 91-179 degrees, not 181-360.
There need not be any, and all six can be obtuse.
Some letters fit into more than one group. Some letters depend on the font,such as B D R P etc. Here is my count:11 Right angles: A L T B D E F G H I P R 9 Accute angles: A K M N V W X Y Z3 Obtuse angles: K X Y
