URGENT** Will mark brainiest if you help soon I know this is a lot of writing, but I just want to know if I did everything right

It's a problem where you have to hit the cue ball in pool against the side so it hits the blue ball.

First, label the cue (white) ball A.

Label the pocket the ball has to go in E, in my case, they said the lower, farther right one.

Draw a line segment from E to the other side of the pool table you have to hit the cue ball to. Label that endpoint C.

Draw another line from C to A.

It then says to draw a perpendicular line segment from A to the same side of the table as C and label the endpoint B (this is what I'm confused on)

Draw a line from C to B

Draw line D to complete triangle CDE which is similar to ABC. Label vertex D and mark the angles that have the same measure

Identify lengths AB, CD, and DE. The dimensions of the pool table are on the picture. (if you could figure this out, it would help a lot!)

Because this is not all of the things I have to do for this, I'll make a separate question, if you know how to do this, please see that question too
