A submarine is 319 m horizontally out from the shore and 111 m beneath the surface of the water. A laser beam is sent from the submarine so that it strikes the surface of the water at a point 209 m from the shore. If the beam just strikes the top of a building standing directly at the water’s edge, find the height of the building. The index of refraction of the water is 1.333 . Answer in units of m.
