Answer:
In parallelogram adjecent angles are supplymentry because opposite sides are parallel to each other and adjecent angles are internal angles of parallel sides
Step-by-step explanation:
Therefore
angle A + angle B = 180....... adjecent angles are supplymentry in parallelogram
3A=2B.....(1)
A=180-B....(2)
3(180-B)=2B....... from (1) and (2)
540-3B=2B
540=2B+3B
540=5B
B=540/5
B=108....
In parallelogram opposite angles are same
and D and angle B are opposite angles
Therefore..
angle D=108
