Answer:
Choice B, 46°
Explanation:
Knowing that minor arc UV, is 38°, and that both arcs, UV and XY are connected to the angle of 42° from point Z, you would do the inverse of what was done at minor arc UV.
Since arc UV was an arc of 38°, with the angle m∠UZV being 42°, there was a 4° reduction in the angle.
Because arc XY, is similar to arc UV, you'll simply add 4° this time to 42°.
42° + 4° = 46° (Choice B)
