I had guessed at that answer, as I did not know how to do it.
Upon trying this problem later, I was able to prove statement #2, but unable to prove Statement #1.
The correct answer choice is D.

think might have came up with something
there is a semi circle, therefore it is 180 degrees
angle COD is 60, therefore, angle AOC has to be 120.
Since Oc = BO = AB are equal (radius)
angle BAO = angle BCO
im not sure if this is right

Even if angle BAO = angle BCO, given statement 2 alone. You do not know the degree of BCO do you?hongwang9703 wrote:think might have came up with something
