You're standing 1.5 m horizontally from the edge of a 4.2 m -deep lake, with your eyes 1.7 m above the water surface. A diver holding a flashlight at the lake bottom shines the light so you can see it.
Part A
If the light in the water makes a 44o angle with the vertical, at what horizontal distance is the diver from the edge of the lake?
