∠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°

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

answer is c

step-by-step explanation:

81/12=324/x

x=48
