Answer: DB is 5
Step-by-step explanation:
Alright, lets get started.
Since given that AD is parallel to CB.
And AB is parallel to CD.
And the angle A is given as 90°
It means the given figure is a rectangle.
And the diagonals of the rectangle are equal to each other.
So, 
So, 
Hence the answer is 5 ... Answer
Hope it will help :)

Answer:
yes
Step-by-step explanation:
The figure can be shown to be a parallelogram by showing the sum of endpoints of the diagonals is the same.
A +C = B +D
(0, 6) +(0, -4) = (0, 2) = (3, 5) +(-3, -3) . . . . diagonals bisect each other
If the diagonals of a quadrilateral bisect each other, it is a parallelogram. A parallelogram with a right angle is a rectangle. So, ABCD is a rectangle.

<em>Additional comment</em>
The midpoint of each diagonal is half the sum of the end point coordinates. That is, the midpoints are (0, 2)/2 = (0, 1). Since calculation of the midpoints requires both sums be divided by 2, we can tell the midpoints are the same if the sums are the same.
