ABCD is a parallelogram find x+y.​

Answer 1

Answer:

write correct question

Answer 2

Answer:

x=60

y=40

Step-by-step explanation:

Here, ABCD is a parallelogram.

∠CBD=40  

o

 and ∠BAD=80  

o

.

AD∥BC and BD is a transversal.

∴  ∠ADB=∠CBD            [ Alternate angles ]

∴  ∠ADB=40  

o

.

∴  y=40  

o

.

In △ADB,

⇒  ∠ADB+∠DBA+∠BAD=180  

o

 

⇒  40+x+80 =180  

⇒  120+x=180  

⇒  x=180 −120  

⇒  x=60  

We get, x=60  

 and y=40
