Draw this description out on a piece of paper if you would like. I cannot figure this out, it has been years since I have done math at this level.

I am standing at point A and have a distance of 87.8333 feet to Point B, my azimuth bearing is 123 degrees. I want to move over 20 feet and find the bearing to the same point B, this distance will also be 87.8333 feet. So I want to triangulate. The question is: What would my new azimuth bearing be to get to Point B, also please show how to solve. Note: I am dealing with geomagnetic bearings, no need to convert to True North.

Thank You

Oh my goodness, after posting above I was sitting here thinking and I remembered 2 pi r squared.

so 2 x r x pi = circumference Divided by 360 times 20 gives me the new bearing. basics basics, thanks anyway to all of you.
