I think i said A because i thought sin(180-B) = -cos(B) and so used the sine rule with a + instead of a - to account for my negative angle. but hey, could be completely wrong :D

...thinking about it now, my reasoning seems completely wrong. oh well, one less mark
Answer is A. cos(180-B) = -cosB

Thanks! But I have to admit, you're a beast for someone who only does Ext 1 Maths!
Lol cheers mate, i did 4u for half a year then dropped it. Half laziness (never touched a piece of hwk and staying back was a bitch) and half too difficult.

Was one but my school cut it out. school cut out probability as well. From what i see here, general consensus is that probability was the hardest question..hardest question for me was seeing the similar triangles in the water tank question.
