Yarr!

Fuck man, I love math. Maths. Whatever. It's just so...perfect! And the numbers line up and do exactly as they're supposed to, and then Bam! Finished math test, without ever having stopped to think.

And I'm *good* at it. I love being good at something that people tend to have trouble with, it's just soothing to know that I'm not a complete waste of Earth. And of all the things in the world to be good at, I love that it's simple sums, just adding and subtracting and multiplying the numbers in my head until they do exactly as I say.

Math is soothing, is what I'm trying to say. I enjoy it. The classes I've had so far this year that I've liked the most have been the ones where I go in and take a maths exam.

In short, eight AM statistics exam, after a night spent up late watching Coupling? Still didn't stand a chance. I kicked that exams ass so hard that it had to go import some cheap, lead painted ass from China, just so I could kick that too.

I've got it narrowed down to a set of 4 linear equations in 4 unknowns which (unfortunately) don't seem to nonsingular. But it appears to be a tighter constraint than 0° < x < 130°

I have:
<CDE + <DEC = 160&deg; <DEC + <AED = 150&deg; <AED + <EDB = 130&deg; <EDB + <CDE = 140&deg; At this point, I realized that there must be some relationship, probably involving triangle ACB being isosceles, that I'm unaware of. The next rabbit hole I'm tempted to run down involved bisecting <DBE to get point F, with FE parallel to BA, and see if that gives me any more promising relationships. It does... It gives me an upper bound x < 70&deg;

Interesting. I got my upper bound of x < 70° in a completely different way, having to do with the fact that AD < BE. So I agree with your finding.

Running headlong down the trail of extrapolating information about the relative lengths of different line segments from known angles has yielded x < 65°, but I'm a lot less confident I didn't mess anything up here.

I haven't come up with anything which gives me a lower bound on x other than x > 0° yet. An insight on that could be heartening.

I also played with bisecting <ACB (or raising an altitude to intersect C). Unfortunately, it doesn't seem to generate anything I can use.
