+421 By vertical angles, w=56˚.
Draw a line parallel to each of the vertical lines that passes through the middle vertex.
Then
So y=180-68-56=x.
so w=56
y=x=56
b=68

+1639 Something's missing here!!!
The sum of those two (given) angles is 180º, but that does not necessarily mean that the perpendicular lines are parallel!!!
+36916 I don't think I can solve this unless I assume the vertical lines ae parallel.....are they stated as being parallel?
