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
ans:D

A)80
B)70
C)40
D)30
E)10 We see that x + y - z = 180, so: 100 + 110 - z - 180 210 - z = 180 z = 30 Answer: D
