Best ResponseYou've already chosen the best response.0Assume the start is at (0,0) The end is at (22,53).  direction = tan^1(53/22) = 67.46 But the angle is in the 2nd Quadrant. So, direction = 67.46 + 180 = 112.54 degrees. Is this right?

Best ResponseYou've already chosen the best response.1I got an angle of 22.5 degrees West of North, that would resolve to a bearing of 36022.5 degrees or 337.5 degrees on a compass.

Best ResponseYou've already chosen the best response.1Taking in consideration that North is 0 degrees, I say you got it right.

Best ResponseYou've already chosen the best response.1Note that direction, North is 0 degrees and then you rotate clockwise, East is 90 degree, South is 180 degress etc.
