measure of arc XY

The arc ZV is 43 degrees. Since angle ZWV is 90 degrees, arc ZY is 90 - 43 = 47 degrees. Since angle YWV is 90 degrees, arc YV is 90 - 47 = 43 degrees. Angle XVY is inscribed and subtends arc XY. Angle XVY is not given. However, arc ZY is 47 degrees. Angle ZVY is inscribed and subtends arc ZY. Angle ZVY = 47/2 = 23.5 degrees. This is not helpful. Angle ZWY = 90 degrees, so arc ZY = 90 degrees. This contradicts the 43 degree marking. Let's re-examine. Angle ZWV = 90 degrees, so arc ZV = 90 degrees. Angle YWV = 90 degrees, so arc YV = 90 degrees. Angle ZVY = 43 degrees. This is an inscribed angle subtending arc ZY. Therefore, arc ZY = 2 43 = 86 degrees. This contradicts the diagram.

Let's assume the 43 degrees is the measure of arc VY. Then arc VY = 43 degrees. Angle YWV = 90 degrees implies arc YV = 90 degrees. This is a contradiction.
