The Answer is D 30 degrees :

x = 100 ( Looking at the Figure we can say that x & the angle subtended between y & z Sum is 180 degrees)

Equation is 100 + 110 - z = 180

considering the angles on a straight line,
x+y-z=180
100+110-z=180
z=30

We see that x + y - z = 180, so:

100 + 110 - z - 180

210 - z = 180

z = 30
