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 DFC?
A.
110°
B.
125°
C.
145°
D.
160°
B. 125°
Since angle BFE is 35 degrees and it is a right angle, angle EFD is 90 degrees. Therefore, angle BFD is 90 + 35 = 125 degrees. Since line B-D and E-C intersect at point F, angle BFD is equal to angle DFC. Therefore, the measure of angle DFC is 125 degrees.
