Lighthouses help ships see to avoid rocks along the coast. They can also be useful navigation references to help ships stay far out from shore in deep enough waters. The captain of the boat knows he needs to stay at
least 1500 meters from shore. He sees a lighthouse that his charts say is 35 meters tall and measures the
angle to the top to know how far away he is from the shore. What angle will tell him he's about to get too
close to the shore?
