Line AB is parallel to line CD. What is the measure of angle CFE? A 45°
B. 55°
C. 125°
D. 180°

c

Step-by-step explanation:

A full circle is 360 degrees so half way would be 180 and since theyre parallel you know that you can use the 55 degrees up top to use in ur equation to find cfe

180-55=125

Can't be 45 because the angle on the other side is smaller than cfe and its 55 degrees and cfe has to be wider than 90 degrees because a right angle is 90 degrees and this angle noticeable goes past 90

Can't be 180 because the whole thing equals 180
