B. 3 5/12

C. 3 4/9

D.4

4

Step-by-step explanation:

(1+2) +( 2/3 + 3/9)

3+1=4

∠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°
