Consider the image attached.
The angle x (in black) and x (in red) are identical as they are vertically opposite angles.
Now we can say that w - 1 + x = 180 (add up to straight angles)
We can also see that w + 1 + y = 180 (add up to straight angles)
So when we compare them we can see that x > y.
The answer is A.
The angle x (in black) and x (in red) are identical as they are vertically opposite angles.

- x = 181 - w
We can also see that w + 1 + y = 180 (add up to straight angles)
- y = 179 - w
So when we compare them we can see that x > y.
The answer is A.
