Answer:
Angle BFC = EFD.
So, Angle AFE = AFB + 2(BFC) + CFD
AFE = 25 + 2(57) + 34
AFE = 25 + 114 + 34
AFE = 139 + 34
AFE = 173
So B is correct.
Let me know if this helps!
The answer would be 20% divide 9 by 45 and you get the answer of 0.2. When we use percents, we multiply the value by 100 so 0.2 x 100 you move the decimal over 2 places to the right. This means it would be 20% of the whole.
You would add all the sides together
