Answer:

x + y = 170

Step-by-step explanation:

Using the vertical angle theorem, you can find out that:

x + y + 110 + 80 = 360.

You can simplify this to find x + y.

x + y + 110 + 80 = 360

simplify

x + y + 190 = 360

-190 both sides

x + y = 170
X and y are both 70 When you add them together you get 140
