Am I*

AB? Yeah it looks like that one is!

anonymous · Answer

The major measures more than 180 degrees

anonymous · Answer

i was going to say, either you are right if the major is the whole remaining angle, or it is 180-45.

what not 360 -45 

if you take a 45 degree arc out of the circumference, whats left..?

anonymous · Answer

yes go with your first answer, major is more than 1/2 of a circle

Would the answer then be 135?
