Sum of all three angle of a triangle is 180.
So, X + Y + Z = 180
30 + 110 + x = 180
140 + x = 180
So, x = 180 - 140 = 40...
So, X + Y + Z = 180
30 + 110 + x = 180
140 + x = 180
So, x = 180 - 140 = 40...

(Angle x) + (Angle y) + ( Angle z)
Angle sum property
30+110+z= 180
140+z=180
z=180-140
z=40
Therefore Z is equal to 40 degree
