1) all the angles opposite the vertex are the same, therefore te ngle w opposite to 110 ° is equal, then

you have  y° = 180 -(110°+30°) = 180°-140° = 40°,

as the line AB is parallel to CD them  W Y Z are angles alternes and interns then  Z = W, Z = 110

NOW  X+Y+Z =180°

X+Z+30 = 180

X+110+30 = 180

X= 180-130 = 40
