Answer:
x = 120 degrees
Step-by-step explanation:
angle below x is 40 degrees because it is a corresponding angle.
x = 180 - 40 - 20 = 120 degrees
x=120 I believe
so using the left side, we can form the equation x+20+_=180
x+_=160
we know the 2 lines that are parallel, and they have a line through it (idrk what it's called)
_=40
x+40=160
x=120
