What is mDFC?
45°
80°
125°
135°

I think the answer is 80 because it is bigger than 45 but smaller than 125 so then it couldn't be 135 either so you have 80.
Answer:
Option B is correct .i.e, m∠DFC is 80°
Step-by-step explanation:
We are given measure of ∠ BFC = 45° and measure of ∠AFE = 125°
We have to find measure of ∠DFC
From Figure,
Line BE intersects with line AD at point F.
we know that vertically opposite angles are equal
So, we get
∠BFD = ∠AFE
∠BFC + ∠CFD = ∠AFE
45° + ∠CFD = 125°
∠CFD = 125° - 45°
∠CFD = 80°
Therefore, Option B is correct .i.e, m∠DFC is 80°
