Question

In the given figure, ABCD and ARTS are
parallelograms. Find x and y.​

Answer 1

Since ABCD is a parallelogram, AB∥DC and AD∥BC

Now, AB∥DC and transversal BD intersects them.

∴∠ABD=∠BDC since alternate angles are equal.

⇒10x=60

And, AD∥BC and transversal BD intersects them.

∴∠DBC=∠ADB

⇒4y=28
