Answer:
125 degrees
Step-by-step explanation:
We can use triangles to help us. In this case since we need Angle WXY let's use triangle WXY.
Since we are given that Angle ZWY=43, we can use this to determine that Angle XWY=43.
We are also given that XYW=12.
Since angles in a triangle add up to 180 degrees...
Angle WXY = 180-(43+12)
Angle WXY = 180-55
Angle WXY = 125
