The 3-point line in basketball is 23 ft 9 in away from the point on the floor vertically below the center of an 18-in diameter rim. The rim is 10 ft above the floor. Kim shoots a three pointer using a 9-in diameter ball from the 3-point line that just clears the basket. The release height was 8 ft. What is the smallest release angle, measured relative to horizontal?
