This data suff. question is based on the diagram, which I've added in the attachment. Here is the question:
In the figure shown, point O is the center of the semicircle and points B, C, and D lie on the semicircle. If the length of line segment AB is equal to the length of line segment OC, what is the degree measure of angle BAO?
(1) The degree measure of angle COD is 60 degrees.
(2) The degree measure of angle BCO is 40 degrees.
I got really stuck with this question. Would you guys please explain each step that you have taken when working on this problem?
yezz, would you please explain how A is suff? I understand how B is, but i'm completely clueless with A. if COD is 60, that means that COA is 120. then where did you go from there? how can you determine BOA before reaching to BAO??
