After a long day of travel, late at night, you swim in the pool of the hotel where you are staying. As you retire to your room, you realize you have lost the key to the pool. You get a powerful flashlight and walk around the pool shining the light on it. The light illuminates the key, which lies at the bottom of the pool, when you hold the flashlight 1.2 m from the surface of the water and point it toward the surface at a horizontal distance of 1.5 m from the edge (see figure). If the water at that point is 4.0 m deep, how far from the edge of the pool is the key?

Question

After a long day of travel, late at night, you swim in the pool of the hotel where you are staying. As you retire to your room, you realize you have lost the key to the pool. You get a powerful flashlight and walk around the pool shining the light on it. The light illuminates the key, which lies at the bottom of the pool, when you hold the flashlight 1.2 m from the surface of the water and point it toward the surface at a horizontal distance of 1.5 m from the edge (see figure).

If the water at that point is 4.0 m deep, how far from the edge of the pool is the key?
