Hi! Can someone help to solve this for me? If the bearing of A from B is 215, what will the bearing of B from A?

The bearing from B-to-A is directly opposite the bearing from A-to-B. There are 360 degrees in a complete circle, so .. how many degrees do you turn to go in the opposite direction? Subtract that from the original bearing and you'll have your answer.

So you have to subtract 215 from 360 to find bearing from B to A because there are 360 degrees in a complete circle.

Wrong - 215 subtracted from 360 is 145, and that is NOT the bearing opposite 215.
