What is the measure of arc XY?

The arc ZV is 43 degrees. The arc ZW is 90 degrees. The arc WY is 90 degrees. The arc XY is the sum of arc XW and arc WY. Since XW is a semicircle, its measure is 180 degrees. However, XW is not a semicircle. The angle ZWV is 90 degrees, so arc ZV is 43 degrees. Angle ZWV is 90 degrees, so arc ZW is 90 degrees. Angle YWV is 90 degrees, so arc YW is 90 degrees. Angle ZWY is 180 degrees, so arc ZY is 180 degrees. Angle XWV is 90 degrees, so arc XW is 90 degrees. Angle XYW is not given. We are given that the arc ZV is 43 degrees. Angle ZWV = 90 degrees, so arc ZW = 90 degrees. Angle YWV = 90 degrees, so arc YW = 90 degrees. Angle XWV = 90 degrees, so arc XW = 90 degrees. The arc XY is the sum of arc XW and arc WY. Arc XY = arc XW + arc WY. Arc XY = 90 + 90 = 180 degrees. This is incorrect. Let's re-examine the diagram. The angle ZWV is 90 degrees, which means arc ZW = 90 degrees and arc WV = 90 degrees. The angle YWV is 90 degrees, which means arc YW = 90 degrees and arc WV = 90 degrees. The angle ZWY is 180 degrees, which means arc ZY = 180 degrees.

This means the central angle subtending arc ZV is 43 degrees. However, we are given that angle ZWV is 90 degrees. So arc ZW = 90 degrees and arc WV = 90 degrees.
