Answer:
1. If AB is parallel to CD and PR is a transversal then,<APR =<PRD (alternate interior angle)
=> 70 +y =100
=>y=100-70
=>y=30
Now, 70+y+z =180 (linear pair)
=>70+30+z=180
=>100+z=180
=>z=180-100
=>z=80
Also, AB is parallel to CD and PQ is a transversal
then, x=70 (alternate interior angle)
2. x= 80 (alternate interior angle)
Now, 80+40+y=180 ( angle sum property of a
=>120+y=180 triangle
=>y=180-120
=>y=60
Also, x+y+z =180
=>80+60+z=180
=>140+z=180
=>z=180-140
=>z=40
