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 dont 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)
