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.

Good luck with that...mared posts questions showing no effort whatsoever and using horrible thread titles and then expects all work to be done with no additional feedback from him/her.

Wow! I've been off the list for quite a while. I didn't realize this poster was not looked on favorably.

Question for MarkFL: If this is the way he/she is thought of, why is he/she allowed to post?

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.
