Answer:

Mark me as brainliest

Step-by-step explanation:

In given parallelogram

AB=CD. and AD=BC

then

2y-1=21

2y=21+1=22

2y=22

y=11

and,

3x=15

X=5

Verified answer

Answer:

AB= DC ( opposite sides of parallelogram is equal)

2y-1 = 21

2y = 21 + 1

2y= 22

y = 22 ÷ 2

y = 11

AD = BC ( opposite sides of parallelogram is equal)

3x = 15

x = 15÷3

x = 5

x = 5

y = 11
