C. 248°
The arc measure of a full circle is 360 degrees.
Arc XZ measures 112 degrees.
Arcs XZ and XWZ add to a full circle, or 360 degrees.
The measure of arc XWZ = 360 degree - 112 degrees = 248 degrees
2/7(x-2)=4x
(2×x-2×2)/7 = 4x
(2x-4)/7 = 4x
2x-4×(1) = 4x × 7 ( Cross multiply)
2x-4 = 28
2x = 32
2x÷2 = 32÷2
x=16
