How do you get the answer for 1/4 divided by 2 by showing your work

Step-by-step explanation:

well you need to do a weird thing. so it's 1/4 divided by 2, so keep change flip. so it turns into 1/4 times 1/2. and that equals .25 times .50. which equals .125!

∠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°
