Answer + Step-by-step explanation:
70+50+z= 180 (Angle Sum Property of △s)
z= 180-(50+70)=180-120= 60
z= 60degree
x= 180-60= 120(Linear Pair angles)
x= 120degree
30+120+a= 180 (Angle Sum Property of △s)
a= 180-(30+120)= 180-150= 30
a= 30degree
y= 180-30= 150degree (Linear Pair Angles)
y= 150degree

y= 150degree
Thus, x= 120degree and y= 150degree.
