# bearings question Watch

1. (Original post by zoxe)
same as tenofthem, how did you know the position of C1 and C2?
Refering to my diagram, its the bearing of A from B, plus/minus theta.

So the diagram in the OPs text book is completely wrong?
It's certainly misleading, C1, so called, is not that close to North.

Mind you, mine's not much better for C2.

Love misleading questions, ending up with acute angles that are clearly obtuse using cosine rule, good old GCSE days
4. I drew my diagram using the fact that theta was 78.6

From this I gather it is still a good thing to take some diagrams with a ton of salt and just concentrate on the algebra and all the details which are written.

That diagram had me puzzled.

That 70 needs to be 180-78.6

After doing these types of questions it seems that I have forgotten a lot of geometric rules learnt at GCSE :\, does anyone have a website which just summarises them?
