Answer:
72°
Step-by-step explanation:
The external angle E is half the difference of subtended arcs CG and DF.
E = (CG -DF)/2
2E = CG -DF . . . . . . multiply by 2
DF = CG -2E = 160° -2(44°) . . . . . add DF-2E to both sides; substitute values
arc DF = 72°
The answer is A. The only way you can get the angle correct is by putting the compass in the center of the circle.

Answer:
about 1.4288993 radians
Step-by-step explanation:
The angle to terminal arm A is ...
∠A = arctan((-4/5)/(-3/5)) ≈ 4.0688879 radians
The angle to terminal arm B is ...
∠B = arctan((-1/√2)/(1/√2)) ≈ 5.4977871 radians
Then the angle between the arms is ...
5.4977871 -4.0688879 ≈ 1.4288993 . . . radians
