Thank you! I have my IG finals next week and I had no idea how to do bearings. Thank you very much.

Can't we just measure the angle at the end, instead of using the cosine and sine rule?

You didn't use sine rule correctly as it is a/sinA = b/sinB = c/sinC so your working out is incorrect

My working is correct as a/sinA = b/sinB is true and therefore can be used. You only ever need to use the a and b part. The c part just tells us that the rule can be used for any two side/angle pairs from the 3 available.

No? he’s right

4:31 if its bearing from the post box isnt that meaning we're stood at the post box about to go to the hall so like the kinda turn we do to get there- so wouldnt the bearing have to be from the post box or am i wrong because it clearly states the "bearing of the hall" ahhh

but then it seems like the next question contardicts it because if applying my logic that the key word "from" implies thats where the bearing comes out from as seen at 5:27 even despite the stating "bearing of y" -so which is it?
