Assuming that a traingle is meant to be a triangle, then the answer is none.
An obtuse triangle can have no right angles, and has two equal angles.
No right triangle can have any obtuse angles inside it.
It can have 0 or 2 right angles, 1 or 2 acute or obtuse angles.
There can be 0 to 5 right angles, or 1 to 6 obtuse angles in a hexagon.
There are 3 obtuse angles. All 3 exterior angles are obtuse. (This is, admittedly, a bit of trick question!)

3... If its a traingle it has 3 angles where the sides meet.
If it is a 'regular' hexagon, then all angles are congruent, and all are obtuse.
None... All 4 angles are right angles (right angle means 90 degrees), meaning the angles are neither obtuse, nor acute.
it has 1
None
A rectangle has four angles, and all of them are right angles, measuring 90 degrees. Consequently, there are no obtuse angles in a rectangle, as obtuse angles are defined as angles greater than 90 degrees. Therefore, the number of obtuse angles in a rectangle is zero.
there are no right angles in a rhombos, but there are 2 obtuse angles and 2 acute angles.
