Answer:

Less than 90

Step-by-step explanation:

All angles in a triangle add up to 180 degrees.

An obtuse angle is an angle that is greater than 90 degrees.

For simplicity's sake, let the obtuse angle be 91 degrees.

180-91=89

The remaining angles in an obtuse triangle are always acute.

Sorry for the trashy answer.
