In$-$Class Problem

Dylan is floating motionless on a raft and sees a pair of goggles on the bottom of the pool that are a horizontal distance of $6$ ft away. Dylan's eyes are $14$ inches above the surface of the water and are looking down at an angle $39$ below the horizontal. Assume the index of refraction of air and water are $1\mathrm{.}00$ and $1\mathrm{.}33,$ respectively. Determine the depth of the pool. Part A what is the angle under the water part B what is the depth of the pool
