Answer:
x=100
y=140
Explanation:
140 (that's the only angle that's shown) -180 (thats a straight line) is 40. that means that the angle that's next to is is also 40.
so 40+40=80
180-80=100
x=100
then you have y!
we know the angle that's connected to x is 100 that means the other two are also 40 so the angle y must be 140
