Question

ab is parallel to cd.find the valueof x​

Answer 1

Answer:

Step-by-step explanation:

given that AB is parallel to CB

Then draw a line MN passing through x

now angle ABX + MXB=180   (sum angles on a same side of a transversal are suplemmentary)

BXM=180-120=60

Similarly DXM+MXD =180

DXM=180-100=80

So, x=80+60=140
