Question

find x and y in following parallelogram​

Answer 1

Answer:

Y=180-60=120,X=180-120=60

Answer 2

Answer:

Step-by-step explanation:

∠ABC = ∠ADC           ( opposite angles in parallelogram are equal)

∴ x + ∠ADC = 180°         ( Angles in a straight line is 180°)

We can now replace ∠ADC with ∠ABC

∴x + ∠ABC = 180°

⇒ x + 60 = 180°

⇒ x = 120°

And y is = 60°            ( interior opposite angle)
