Find arc AB.
A.90
B.96
C.108
D.120

Answer:
C) 108
Step-by-step explanation:
Notice that CD ≅ AB.
If you draw OD, OC, OA, and OB, you will find that OD ≅ OC ≅ OA ≅ OB.
Therefore, triangles ΔAOB ≅ ΔDOC by SSS congruency.
Therefore, CD ≅ AB since the triangles are congruent, the arc passing through them has to be congruent.
Therefore, CD = AB = 108, which is choice C) 108 Ans.
Hope this helps!
