Answer:
The sum of co interior angles of parallelogram is 180
110° + x = 180°
110° + x = 180
x = 70°
x + (y + 40°) = 180°
70° + y + 40° = 180°
y = 180 - 110
y = 70°
The sum of all angles in trapezium is equal to 360°
110° + x + y + z = 360°
110° + 70° + 70° +z = 360°
z = 360° - 250°
z = 110°

Answer: angleZ is 40 degrees(alternate interior angles)
AngleY is 110-40(opposite angles of the parallelogram)=70 degrees
And AngleX is 360-(110+70+40)(sum of a quadrilateral)=360-220=140 degrees
