30-60-90 right triangle. Short leg is the vertical distance from Dolores' height of eye to the water below. Sides are in proportion 
. So if the short leg is 50 feet, then the hypotenuse is 100 feet and the long leg (the desired distance) is 
And next time, show Dolores a little respect -- capitalize her name.
