A girl starts from a point A and walks 285m from B on a bearing of 073°. She then walks due South to a point C which is 307m from A. What is the bearing of A from C?

Let's solve the first question. The wording is a bit ambiguous, but we will interpret "walks 285m from B" as the distance BC, and "on a bearing of 073°" as the bearing of B from A.

: A girl starts from a point A and walks 285m from B on a bearing of 073°. She then walks due South to a point C which is 307m from A. What is the bearing of A from C?

• Let A be the starting point.
• The bearing of B from A is $073^\circ$.
