A ship called FMPC 10 leaves Port on a beautiful blue sky day and sails on a bearing of 145degrees for a total of 19 km. The ship then sails north for 8km to point X. At point X, the ship lets loose a balloon. The balloon rises vertically above point X for 2000m. Note point X is not due east of Port. Bob was left behind at the Port. He sees the balloon. As Bob knows the sailing details of the FMPC 10, he can use Trigonometry to figure out how far the FMPC 10 is from port. What is the angle of elevation of the balloon from Bob’s viewpoint in Port?
