Here's another.Help..

i think the answer is 16

Step-by-step explanation:

bc one side is 8 and the other side looks like its the same length but im not completely sure so don't trust me

Diameter = 8

Radius = 4

Circumfrence = 2pi(r)

Circumfrence = 25.12

Half of the circumfrence = 12.56

Add 8: 20.56

Hope this helps!

∠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°
