A ship is sailing due north. At a certain point, the bearing of a lighthouse 3.83.8 km away is N38.138.1degrees°E. Later on, the captain notices that the bearing of the lighthouse has become Upper S 33.3 degrees E. S33.3°E. How far did the ship travel between the two observations of the lighthouse?

r and t.

both are 64 degrees.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the answer is b
