2)In the movie Star Wars, Luke must hit a small target on the Death Star by flying a horizontal distance to reach the target. When the target is sighted, the onboard computer calculates the angle of
depression to be 28°. If, after flying another 150 km the target has an angle of depression of 42°, how
far is the target from Luke's spacecraft at that instant?
I have no clue how to do this but it is supposed to be done used law of sines and cosines.
