59. Aidan is fishing on a lake. As shown in the figure below, his hook is caught on the bottom of the lake at the end of 60 feet of fishing line that extends from the end of his fishing pole. The angle of depression from the end of his fishing pole to his hook is 20°. If the tip of his fishing pole is 5 feet above the surface of the water, which of the following is closest to the number of feet his hook is below the surface of the water?

(Note: sin 20° ≈ 0.34 and cos 20° ≈ 0.94)
