Answer:
x=8
NR=5 units
BI=10 units 
Step-by-step explanation:
In  a rectangle BRIA
AN=5 units
NR=x-3
We have to solve for x , NR and BI.
We know that 
Diagonals of rectangle bisect to each other.
BI and AR are the diagonals of rectangle BRIA and intersect at point N.
AN=NR



Substitute the value of x
NR=8-3=5
By property of rectangle
BI=AR=AN+NR=5+5=10 unit
BI=10 units
