Answer: Choice A
100 degrees
========================================================
Explanation:
See the diagram below.
Angle WVX = 130 is marked in red.
Congruent vertical angles WVZ and XVY are each x degrees and are marked in blue.
A red and one blue angle combine to 180 degrees.
blue+red = 180
x+130 = 180
x = 180-130
x = 50
The blue angles WVZ and XVY are 50 degrees each.
So they total 50+50 = 100 degrees
