What is mdfc?

45°
80°
125°
135°

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°

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

this is not the answer this is just a question. is this middle school math?
