Answer:

AC = 8 units

Angle CDB = 67°

Step-by-step explanation:

The given figure represents the data given.

From figure we can see that BD = AC

Length of AC =  8 units

We also have

      ∠ABD = ∠CDB

Angle CDB = 67°

See the attached picture to better understand the problem
we know that
in rectangle ABCD 
AB=CD
and 
AD=BC
therefore
the triangle ACD and triangle ABC are congruent
so
BD=AC
BD=8 units

the answer part a) is
BD= 8 units

Part b) Find angle CBD

we know that
∠ABD+∠CBD=90°---------> by complementary angles
so
∠CBD=90-∠ABD-----> 90-67----> 23°
∠CBD=23°

the answer Part b) is
∠CBD=23 degrees
