Yes, use East and North always, then you'll start to develop a method.
So should I always use east and north as my guide?.
and the bearing angle with
Unfortunately, the bearing may not come out correctly from the atan because (for example) atan(1) may be 45 or it may be 225. There is no way the calculator can 'know' which answer to use; so you'll have to look at the diagram to decide on the correct bearing. eg. If you get 45 and you can see the answer should be SouthWest you can correct your answer by adding 180.
In your example
first stage East = 0 North = 10
It seems my inability to know the bearings always cost me.
I used zeros for the unprovided bearings. And got every thing wrong. I don't know any method well, apart from the vector approach. I don't seem to understand your workings, but see how I did mine:
I did use the vector approach much like you. I haven't kept my working (on Excel) but the shot below shows my working to get the missing bearing on the previous question.
Please produce them here.
But please, did you use the vector approach? If so, please show me the workings, that I could learn.
I was waiting for your answers. I have now done the calculations and I get the same.
My final answers are different from what the book has. I used vector approach though. This is the respective answers from the book.
OK. So, do you have an answer?
This is it:
Yes, I have had it right! I missed it up then. I would post more in which distances and bearings are not given.
60 is the angle with an easterly direction. 0 is the angle with a northerly direction. So you have muddled the components.
There are several examples in the book, which there is no distance and bearing of locations provided,
