If 1 measures 135°, what is the measure of 8? (Lines b and c are parallel.)
45°
135°
67.5°
65°

Answer:
135
Step-by-step explanation:
1 and 4 are vertical angles. Because lines b and c are parallel, 5 and 8 must also be vertical angles. Not only that but they must be the same vertical angles. 1, 4, 5, and 8 are all 135 degrees.
