|dw:1344308969474:dw| it's not the perfect picture, but you can solve it if u make it like this.
It's all due to the vertical angles theorem. Do you understand?
You made up random lines @_@lllll
I can draw another pic if this one isnt clear........
But it's still solved the same way...
But one thing doesn't make sense in your diagram. How did you get the 133s in the left bottom and right upper hand?
But thats, assuming that it crosses at the same angle.... and, as to that question, I didn't have enough space to write it where it was supposed to be, which was above that line... but That angle is of no consequence... I guess I went a bit overboard there....
But by creating new lines, I got 141. If you add a line you'll see that alt interior angles are congruent which will also create a triangle in which you can find 2 of the angles via supplementary angle (180-x) so that you can find the last angle by triangle=180 degrees. then you find the other supplementary angle
Lets just use my second pic.... its much more simple to use, k?
Oh wow, sorry, simple mistake on my part.... I accidentally subtracted the wrong number...
Well, now you have the answer, through trial and error, right?
I didn't really look at your diagram xD
You went MIA on me.... ok. bye!! and ttyl!!
I think there is another solution to this but I don't remember it. It's best not to create new lines as it makes things more complicated
