Damn, nice, U take math HL at Ib ?
It was an easy question though, damn Haese and harris book, doesn´t prepare you for the difficult questions
Btw how did you get that answer?
lol, do you take it at HL then? coz no offence, but if you cant do a 'nice easy question' then oooh dear...
and i used the ambiguous case rule + you find the obtuse angle which it could also be, to then find out what other length it could be.

I completely disagree. I took IB exams last year with that textbook and it was a fantastic resource, especially for calculus and statistics. You need to learn how to spot the ambiguous case, and it's quite an easy thing to do PROVIDED you go through past papers/a questionbank. The method is actually right in the textbook...NUMBERED.
