Question

find x if ab parallel to cd ​

Answer 1

Answer:

first we need to draw a line that is parallel to ab and cd and  passes from x and it divides x into two parts x1 and z2

LET THE LINE BE FG

then since it is parallel so

angle A + angles AEG= 180

so here we get x1=60

and similarly when we do for angle c and angle CEG,we get 60

when we add them , we are adding the two parts i.e x1 and x2

hence the ans is 60+60=120

please mark me brainliest if it helped you
