To find the measure of angle 7, we need to use the vertical angles theorem which states that vertical angles are congruent.
Since angle 6 is 140 degrees, angle 7 will also be 140 degrees. Therefore, the answer is:
C. 140 degrees
If m 6 = 140 degrees, what is m 7?
A. 40 degrees
B. 50 degrees
C. 140 degrees
D. 180 degrees
