Which set of points represents a function? O {(8,6), (0,5), (0,9), (3,3), (7,8)}
O {(7,8),(0,3), (8,5), (0,6), (9, 2)}
O {(5,5), (4,5), (9,5), (2,3), (6,8)}
O {(9,1), (7,0), (4,6), (9,8), (8,5)}

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
