This question would be best answered by the use of a diagram but the first thing to do is understand that a right angle triangle is formed if the ship sails west and then south. With right angle triangles we can use trigonometry to find one of the acute angles formed. The angle would be the tan of 20/18 = 48 degrees. We must then take this angle and the 90 degree angle formed by going in a west direction from 360

S the final answer is 360 - 48 -90 = 222 degrees
