4. Find the values of x and y in the following figures I, II. It is given that AB || CD and transversal
intersects them.
​

Answer 1

Answer:

1 ) x = 55, y = 125 ; 2) x = 120 , y = 60

Answer 2

Answer:

1. x= 55° (vertically opp. angle)

interior angles= 180 - 55 =125°

y= 125 (v.o.a)

2. 60°+ x= 180 ( linear pair)

x= 180-60= 120°

y=60° (alternate interior angles)
