I have 2 points with bearing's coming from them, I need to calculate a 3rd point(intersection of bearing's from point 1,2) but am unsure of the maths required to do this. Could someone give me an example of how to do this.

Edit - The bearing's I am referring to are degree's from north. So I have point A + Point B and an imaginary line coming from from each point on the a particular bearing. I wish to know at what point the imaginary lines would cross.

To explain further -

I have point X,Y on a map and a bearing to an object(point 3) from point 1, I also have point 2 on the map and a bearing from point 2 to the same object (point 3) as point 1. what I need to do is to calculate the X,Y for point 3 using points 1,2. If it helps I would imagine the max distances between point 3 and points 1,2 would be a mile or so.

Maths was never my strongest point so if someone could explain how to do this in basic steps that would be great

Thanks

    What do you mean by "bearing's"? Rays? Spheres?2011-05-09

    On a sphere/globe or on a plane?2011-05-09

    "bearing" - "direction"?2011-05-09

    "bearing" is usually, I think, direction given as an angle clockwise from North. Doing the problem, however, requires knowing whether we're working on a sphere/globe or on a plane.2011-05-09

    Points do not intersect. Rays from points or lines through points intersect.2011-05-10

    Colin, but you could upload a pic to e.g. http://imgur.com and provide a link. Someone else can then include the pic into your post for you.2011-05-10

    What are the bearings with respect to? I don't see a convenient reference that bearing 1 is 50 degrees from, nor that bearing 2 is 20 degrees from. Angles are between two things-I was taking up as the reference, but other conventions are possible.2011-05-10
