Second part of the Pool table problem If you could tell me how to find CD and DE first that would be great! To figure out these questions, that is needed. The proportions for the pool table are on the picture.

Use your similar triangles to set up a proportion. Solve this proportion for the unknown variable, the length of BC.

To make your shot, you need the cue ball to hit point C.
Find length CD and use it to identify the location of C in relation to one of the corner pockets. For example, if C is on the upper bumper, your answer might be: 15 inches to the right of the upper left pocket. Round your answer to the nearest inch.
