Asked by Charles

From a place 300m North of A, a man walked eastward to a place B. Which is 600m from A? Find the bearing of A from B.
Answered by Anonymous
Well the bearing of B from A is easy, them add 180 degrees
so
180 + cos^-1 (300 /600) = 180 +cos^-1(0.5)
= 180 + 66.7
= 247

cos^-1(1/2) = 60°
