Pythagorean theorem how to use a water plant to surface, a breeze blowing, floating.
A water plant surfaced, 3 meters above the water surface, and a breeze blew.
Drifting 1 m just submerged, looking for the height of aquatic plants.
If the water depth is x meters, the aquatic plants are (X+0.3) meters.
According to Pythagorean theorem, (x+0.3) 2 = 1 2+x 2,
0.6X= 1，X= 10/3，
So the height of aquatic plants: 0.3+10/3 =109/30 ≈ 3.633 meters.
