Solve the problem.The wind is blowing at 10 knots. Sailboat racers look for a sailing angle to the 10-knot wind that produces maximum sailing speed. This situation is now represented by the polar graph in the figure shown below. Each point (r, ?) on the graph gives the sailing speed, r, in knots, at an angle ? to the 10-knot wind. What is the speed to the nearest knot, of the sailboat sailing at 30° angle to the wind? 
A. 4 knots B. 5 knots C. 2 knots D. 3 knots
