answer
84 degrees
set up equation
in a circle, the inscribed angle theorem states that the inscribed angle is half the intercepted arc
angle X is the inscribed angle
arc WV is the intercepted arc
inscribed angle = intercepted arc/2
X = WV/2
values
X = 42
plug in values and solve
42 = WV/2
WV = 42 * 2
WV = 84 degrees
