The picture is somewhat unclear. What do the big dots mean? Is the line between 6x and x a median to the other side?

I think the dots mean that those segments are equal. Specifically, the segment joining the angle x with the angle 2x is the same length as the segment directly across from the angle 6x. Under that assumption, you can use the law of sines and various sum to product identities to get that x = 15 degrees.

This opinion is not actually agreed upon by consensus, it is just an observation of mine. We really only ban spammers and those who might post in a horribly inflammatory manner. I simply choose not to post any kind of help for this user. I have repeatedly asked this user to use better thread titles, and all such requests have been ignored. For example, the original title of this thread was simply "x"...indicative of minimal effort made on the part of the OP, along with no effort ever having been shown when posting questions and no feedback given to those who try to help. If this user were to join the site I administrate, I would in fact ban them.
