Measuring the depth of a lake:
3. You need to measure the depth of a large lake. Since the sonar equipment is very expensive, you decide to u
your friend's boat. The boat has an anchor on a 100 ft line. You take the boat out to the middle of the lake o
windy day. You drop the anchor and let the wind push the boat until the anchor line is tight. Your GPS tells yo
that the boat has moved 82 feet. Assuming the bottom of the lake is flat, what is the depth of the lake?
Simplify your answer (this is an EXACT answer, so breakdown your radicand and bring any numbers outside t
radical that you can), then, round (approximate) it to the nearest foot.
