Okay, I'm not sure how I'm really going to explaing this problem, but I'll try. It's really confusing, and I'm not sure that I understand it correctly.

106' F

65'

D A

27' O 62'

E

C

B

It's a circle, O being the midpoint, and A, B, C, D, F are points on the circle. E is the intersection of C-F and B-D, the other chords are D-A, A-O, B-O. The (') stands for degrees, since I can't find a degree sign anywhere on my keyboard.

I hope that this makes sense, ask if if doesn't.

Now for the actual problem. I have to find:

m/BOA =

m/BDA=

m/DEF=

I would think, BOA would be 62', BDA = 62', and DEF = 106'. Apart from the fact that that seems too easy, BOA and BDA are totally different angles. How can they be the same measurment? But on the other hand, I have no clue how to solve it if that's the case.

Anyone know? I'd appreciate the help!
