Question

plz answer with steps​

Answer 1

Answer:60° angle y

Step-by-step explanation:AngleX will be 100 degrees because DC and AB are parallel to each other.

Now angle Y = 360°-(120+100+80)=60°

HOPE THAT HELPS YOU

Answer 2

Step-by-step explanation:

100°+angleABC=180 ° (Linear pair)

angle ABC=180°-100°

angle ABC=80°

Now, DC||AB

.•.x=100°(Alternate interior angles)

Now, In quadrilateral ABCD, By angle sum prop. of quadrilateral

angleA+angleB+angleC+angleD=360°

120°+y+100°+80°=360°

y+120°+180°=360°

y+300°=360°

y=360°-300°

y=60°

Hence, x=100° degree

y=60° degree
