Answer:
An obtuse triangle has all different measurements, which leaves your last two answers out.
If the angle at vertex B is obtuse, that means that the other two angles has got to be less than 90 degrees, because a triangle is 180 degrees, and your angles can't be more than 90 otherwise, you won't have a triangle.
Your answer is less than 90 degrees.
Hope this helps ;)
