Never. If this was true, then the sum of the angles in the triangle would be greater than 180 degrees.

If a triangle had a right angle of 90° and also an obtuse
angle which would be more than 90°, that would mean that only
two of the three angles would have sum more than 180° and the 
third angle added to those would make it have even still more 
than 180°.  So the question boils down to this:

Can a triangle have the sum of its three interior angles to
be more than 180°, or must they add up to exactly 180° no
more and no less?

Since the three angles of any triangle must have sum 180° and
never more than 180°, the answer is "never".

The sum of the 3 angles of a triangle = 180 deg.
Since an obtuse angle is greater than 90 deg., the sum of the remaining 2
angles must be less than 90 deg.
Since a right angle = 90 deg., a triangle NEVER has a right angle and an obtuse angle
