Use the diagram to determine whether you can assume the statement. Points A, B, C, and E are coplanar.
Yes or no

Yes

Step-by-step explanation:

Mathematically, when points are co-planar, what it means is that they exist in the same plane

Now, looking at the 4 points, we can see that they exist on the same x-like plane that is both perpendicular to like H through C

Hence, we can simply opine that these points exist in the same plane and are essentially co-planar

∠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°
