If L1 || L2 and L2 || L3, and the angle between a transversal and L1 is 50, and the angle between same transversal and L3 is x, find x if it is an alternate angle.
A40 degrees
B50 degrees
C130 degrees
D180 degrees
✓ Correct Answer: B — 50 degrees
Since L1 || L3 (transitive property), alternate angles are equal.
