find the size of unknown angles
please help to solve this

Answer:
2x = 120°, x = 60°, y = 60°
Step-by-step explanation:
2x + x = 180° (eternal angles in a parrallel lines add up to 180°)
3x = 180. divide by 3 in both sides.
x = 60
therefore:
2x = 2(60) = 120°
x = 60°
y = x (crossponding).
if x = 60°, then y = 60°
Done :D
