    Thanks. I hope not. But it's right here in the CGP revision book : (
    It's most likely an oversight by the textbook authors. Seriously, don't worry about it for the exam!

    I understand what you mean, but what if you go to solve the Q angle first? Then you'd be thrown right off. There's no guarantee that a student will go to solve one angle first. I suppose you can only use the 180 degree total thing when the first angle you solve is actually correct.
    Yes you have a good point.
