At 8 a.m., a ship which is sailing in a direction 127訊 at a speed of 8 knots observes a lighthouse in the direction 037訊. At 10 a.m., the lighthouse is observed on bearing 340訊. Find the distance of the lighthouse from the ship at each point of observation.

Ummm can anyone show me how the diagram is drawn (ive tried a few times but it seems wrong)?
