The beam of light hit the dolphin at the common point that is the solution of a system:
.
From the second equation express y: y=10-x and substitute it into the first equation:
.
Therefore, the horizontal distance in feet is x=5 ft and the height above water is y=10-5=5 ft.
Answer: the beam of light hit the dolphin at 5 ft above water
