GUESSTIMATE! We know the diagram is drawn to scale because it doesn't say underneath that it's not. All those arcs LOOK about the same length (that is, arc
AB looks like arc
BC which looks like arc
CD, etc.), so all you need to do on this question is count the small arcs that go into the big arcs. They want the ratio of arc
ABC (which is 2 small arcs) to arc
AEC (3 small arcs). The answer has to be (B), 2 to 3.
