The figure below shows ray
and two lines that intersect at point F.
Lines B-D and E-C intersect at F. The angle E-F-B divided into a right-angle and 35 degrees.
What is the measure of angle dfc ?
A.
110°
B.
125°
C.
145°
D.
160°
C. 145°
Angle DFC is the sum of angle EDF and angle EFC. Given that angle EFB is divided into a right angle and 35 degrees, angle EDF is 90 degrees and angle EFC is 35 degrees. Therefore, angle DFC = 90 + 35 = 125 degrees.
