b. EF
c. CBF
d. DEF
3)
What is the measure of angle EAD?
4)
Find the measure of arc EF.
5)
What is the measure of FCE?

Answer 1

1) Circle A (because A is the center)

2) A minor arc is smaller than a semicircle so EF, CBF, and DEF

3) 180 = EAD + 90 + 52

180 = EAD + 142

38° = EAD

4) angle EAF = 180 - 60, or 120° so arc EF should be 120° (I believe)

5) arc FCE is opposite of EF so 360 - 120 = 240°

Answer 2

Answer: Circle A, EF is a minor Arc, EAD = 45 degrees, Arc EF= 150 Degrees, and FCE = 210 I guess from the looks of the Picture.
