Sorry about this, I know I'm not supposed to post a straight up problem, but I really just don't understand any thing here. Any way, I have a home work assignment and related test that involves the relations between circles, arcs, cords, tangent lines, secants, angles, etc. I get it when I know the center (usually), but on a problem like this I get stuck. Since its too hard to describe as its a really complicated figure, I'll put a link to a Flickr page with a scanned version of the problem. If the photo is too small, hold ctrl and zoom in with the mouse wheel. Thanks guys.
