Answer:
BD = 28
CD = 22
A = 124
C = 56
D = 124
Step-by-step explanation:
The above quadrilateral is a parallelogram
(1) Opposite angles are equal.
(2) Opposite sides are equal and parallel.
(3) Diagonals bisect each other.
(4) Sum of any two adjacent angles is 180°
so
BD = AC = 28
CD = AB = 22
A = 180 - B = 180 - 56 = 124
C = B = 56
D = A = 124
