Answer:
152
Step-by-step explanation:
[tex]m \angle {WYZ}=104[/tex] is given, and the angle next to it is a supplement. (Unfortunately, that angle can't be named in the usual way because there is no labeled point "southeast" of point Y.)
That angle has measure 180 - 104 = 76.
Now arc WXY's measure is twice the measure of this angle, so mWXY = 2(76) = 152.
