Question

In each of the following figures
AB is parallel to CD. Find the unknown angles, giving reasons.
plz answer correctly u will get many points from me.

Answer 1

In 1st
On line AB BD ray stand and
Now ABD+x=180
ABD=100
So x=180-100(linear pair)
X=80

Two lines AB and EF
FYB=120 so y=120(vertically opp angel)

Y=120 and corresponding angle is also 120
And y+z=180(linear pair)
120+z=180
Z=180-120
Z=60

T=x=80(Alternatively interior angle)

In 2nd

T=120 (vertically opposite angle)

T=y=120(Alternatively interior angles)

In fig
Doh=50 and it's corresponding Bmh=50
X=Bmh=50(vertically opposite angle)

X+z=180(linear pair)
50+z=180
Z=180-50
Z=30

Answer 2

86+26ty=56 and 56£= 90@
