Answer:
Part 2: 120 degrees
Step-by-step explanation:
Line SY and TZ are parallel and they are being cut by a transversal. Alternate interior angles are congruent, so the angle SVW is also equal to 3x. A straight angle forms 180 degrees. so 6x+3x=180
9x=180
x=20
Angle YVW is 6x, so 6 times 20 is 120
