Let a be a rational number and b be an irrational number. which of the following are true statements?

if he has no friends he cant give them out to his friends

step-by-step explanation:

no friends = cant give anything out

∠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°
