'ls for a distance of to a point B on a bearing of 1a boat leaves a dock at point A and trave35 degrees. the boat then changes course and travels for a distance of 8km to a point C on a bearing 060 degrees.'.

Answer 1

no idea what a heading (not bearing!) of "1a" is.

I also don't see a question in there yet.
Nor the distance to point B.

In fact, the whole things is garbled. Better clean it up if you expect any meaningful help.
