Answer:
D. 86°
Step-by-step explanation:
Points D and F divide the circle into two arcs. The long arc is labeled 274°, and the short arc is the one you're asked to find. You know the total of these two arcs is the full circle, 360°.
274° + DF = 360°
DF = 360° -274°
DF = 86°
__
There are other relationships you can use to find arc DF. One of the simpler ones is ...
DF and the external angle at E are supplementary:
DF = 180° -94° = 86°
