Question

Give the answer for the questions asked.

Answer 1

x= 50 due to ab and cd are parallel so alternate angles .

as exterior angle is equal to sum of 2 opposite interior angle so x+y = 120
y = 70

Answer 2

x=50 (alternate interior angle bcuz AB is parallel to CD)
50+y=120(alternate interior angle bcuz AB is parallel to CD)
therefore y=120-50=70
