Lines $p$ and $q$ are parallel to each other. $m\angle X = 100^\circ$ and $m\angle Y = 130^\circ$. What is the number of degrees in $m\angle Z$?

size(100); real h = 1.2; currentpen = fontsize(10pt);
draw(Label("$p$",Relative(1)),(0,0)--(1,0),E);
draw(Label("$q$",Relative(1)),(0,-h)--(1,-h),E);
draw((0,-h)--h/2*(cos(230*pi/180),sin(230*pi/180)) + (0,-h));
