Answer 2

Answer:AB = 10; BC = 28.

Step-by-step explanation:

It is given ABCD is a parallelogram.In a parallelogram opposite sides are equal.AB=DC and AD=BC.Substituting the given values in terms of x ad y we have:3y-2=y+6

2x-4=x+12

Solving for x y ,3y-y=6+2
2x-x=12+42y=8
x=16.y=4
x=16.AB=3y-2
BC=x+12AB=3(4)-2
BC= 16+12=28.AB=10.
