shallowest part of a lake is 1150', but anyone knows, not at the shoreline. slope is 60 degrees. how far from the shore could one expect go encounter the minimum depth of 1150' ?
Using the Law of Sines, we know: sin(60)/1150 = sin(30)/x; where x is distance from shore
Thus, x = 1150*sin(30)/sin(60) = 663.95'
