Can anybody help me how to draw the diagram of this problem??

Three ships, A, B and C are sailing along the same straight line on a course of 240 degrees. Ship A is at the front, and ship C brings up the rear. From ship A, the bearing of navigation buoy is 025 degrees. The buoy is 2.5 km from ship A and 2 km from ships B and C. To the nearest degree what is the bearing of the buoy from ship C? from ship B?
