Answer:
45
Step-by-step explanation:
Well, it is not 90 degrees, as it is not a right angle.
It cannot be 180 degrees as that would be a straight line and a triangle's whole angle measure is 180 degrees.
It is an acute angle, and appears to be half of 90 degrees, so I would have to say 45 degrees.
Not enough information is false because you can infer that it is 45 degrees by looking at it.
Hope that helps!
