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°

Answer:
No
Step-by-step explanation:
An equation is proportional only if it goes through the origin, meaning the if you plug in 0 for x, you should get 0 for y. In this case plugging in 0 for x gives us 2 for y, meaning it is not proportional.
