Help!!! I don't understand what the textbook is asking AT ALL... can any one help me with this? The rocks near the shore between two lighthouses at points A and B make the waters unsafe. The measure of (arc)AXB is 300. Waters inside this arc are unsafe. Suppose you are a navigator on a ship at sea. How can you use the lighthouses to keep the ship in safe waters?
