Ariel Marks · Answer 1

If B is obtuse, B > 90 degrees, then the remaining two angles add up to less than 90 degrees, so must be acute. In fact, at least one of A and C is less than 45 degrees, but we can't tell which.

Answer: A must be acute

Sanai Michael · Answer 2

Acute. No triangle can have more than 1 obtuse angle.
