Test 3 Section 2 - #7 (page 516)

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.
