Consider kite FGHJ. Kite F G H J is shown. Angle F and H are congruent. The length of side F G is 30 centimeters, the length of side G H is (2 a minus 4) centimeters, the length of H J is 24 centimeters, and the length of F J is (3 b + 6) centimeters. What are the values of a and b? a = 14, b = 6 a = 14, b = 8 a = 17, b = 6 a = 17, b = 8
