Math Exam Woe: Unsolvable Bearing Question

In summary, the speakers are discussing a math exam question that involved determining the distance between two lookout points and a campfire using bearings. However, they are unable to solve the problem due to ambiguity and lack of understanding of the term "bearing." The speakers believe that the question should be changed or clarified for future exams.

So basically, this one question messed me up in my maths exam today. Everything we went over yesterday concerning tangent lines/derivetives I went pretty well in.

The question was. There are two lookout points. A and B. There is a campirefire at a bearing of 40 degrees from A. From point B, the campfire is at a bearing of 20 degrees. From point B, A is at a bearing of 120 degrees. A and B are 10 km apart. Find the distance between A and the campfire.

I tried and tried, but I was unable to do it. Probably because I don't know what bearing is. I thought it meant in relation to north.EDIT: This seems rubbish. Taking these bearings is impossible. If A is located to the left of B, there is no way A's bearing will be more than Bs bearing (in relation to the campfire)

Agreed, the given data is impossible.

Either I read it wrong, or the examiners will need to change the marks. The only thing I can think of is that maybe they meant take the bearing from C, not A/B. But I am pretty sure this is what it said.

I believe this is impossible however you define bearing here, but I suspect the term is ambiguous. I understand the term bearing without qualification to be an angle measured from N clockwise. I think both the reference direction and the sense of the angle may be different in different contexts.

Well either way. It's far too ambiguous for an exam question if you ask me.
