In the diagram below CE=12, DA=12, and EB=9. Find the length of start overline CD. Round your answer to the nearest tenth if necessary.

I don’t have the diagram you mention. Could you either upload the picture or describe how the points/segments are arranged? (Which points are collinear, which segments lie on the same chord or secant, and is E inside or outside the circle?)

To save time, here are the relevant formulas — tell me which applies and I’ll finish the computation:

- If two chords intersect inside the circle at E (chords AD and BC meet at E): AE · ED = BE · EC.
- If two secants from an external point E meet the circle at A,B and C,D (so E is outside): EA · EB = EC · ED, where EA and EC are the external segments and EB and ED the whole secants.
- If a tangent from E touches the circle at T and a secant from E meets the circle at C and D: (ET)^2 = EC · ED.

Once you confirm the arrangement I’ll compute CD (and round to the nearest tenth if needed).
