7. Two ships sail from the same point at the same time. Ship A sails on a course of 175° while ship B sails on a course of 190°. After 4 hours, ship B was 2 miles due west of ship A. If after 4 hours the distance traveled by ship A is x miles, then which of the following equations solves for x? a) x = (2sin 80°)/sin 15⁰ b) x = (2sin 15°)/sin 80⁰ x = (2sin 85°)/sin 15⁰ d) x = (2sin 15°)/sin 85⁰
