Question

In fig. if AB || CD, then the value of x ​

Answer 1

Answer:

your answer is x=80 degree

Answer 2

Given ,

Let the point of intersection at AB be M and  CD be N

LCNM = x (Vertically opposite angle)

Now,

LAMN + LCNM = 180 ( Co-interior angles )

120 + x + x = 180

2x = 180 - 120

2x = 60

x = 30

So, x = 30
