At 8 a.m., a ship which is sailing in a direction 127°T at a speed of 8 knots observes a lighthouse in the direction 037°T. At 10 a.m., the lighthouse is observed on bearing 340°T. 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)?
