WHO says angleACB = 80 degrees?Can anyone help me see why ACB is 80 degrees?
I have tried playing with parallel lines and basic ideas of geometry and some similar triangles stuff.
Any hint please?
WHO says angleACB = 80 degrees?
I get 80.4426.... (close but no ceegar...)
Did you use the Law of Sines?
Can you supply a fully labelled diagram?

Are we to assume \(\displaystyle \overline{AB}\parallel\overline{(Unlabled)C}\)?
yes.
As I'm interpreting it, ABC[D] is a rectangle, and the broken lines are both parallel to BC. Of course, all this should really have been stated.

@tkhunny: The question about the LaTeX code failing was recently posted. The word "angle" automatically connects to a link which screws up the LaTeX. If you put the word (angle) into text before the LaTeX code it will work. For example you could have said the following:
Is it easier to show that the angle \(\displaystyle \overline{CA}\;bisects\;\angle{ECF}\)?

I think you like being in the corner!Yessss......I'm already in the corner.....!!
There was once a mother who cleaned out her teen son's room one day and found a cache of whips, chains, and bondage videos. She asked her husband what to do about it and he replied "Well I wouldn't spank him."

A number of vBulletin bugs act that way. Yet, the conflict between autolinking and LaTeX keywords is consistent. (The site doesn't apply autolinking in previews, so the issue doesn't show up until posting.)Kinda random …
