Just draw a line. Label one end A, one end B. Label the distance as 1km.

From A, roughly draw a 167° bearing and draw a straight line towards a point labeling the bearing. Do the same with B (obviously so it forms a triangle). Label the new point S and you need to find distances AS and BS. You can do this using the cosine rule with 2 angles between a given distance (the coastline = 1km). This is a bit wordy but hopefully it gives you an idea of what to do =]

That doesn't really help me because I don't know how to draw bearings

Also, the final answer is only one distance. So if I find both distances AS and BS, which one do I use?

didn't get how to do this one i tried lol
i did it took a while but my first solution to a question
