The required proof of parallelogram is given below,
What is parallelogram?
A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry. The opposing or confronting sides and the opposing angles in a parallelogram are of equal length.
For a parallelogram, opposite sides are always equal and parallel. 
So for the given parallelogram, we get AD = BC and AD and BC are parallel.
AD and BC is parallel and DC is common side, therefore,  ......(1)
 ......(1)
Given  .......(2)
  .......(2)
Therefore, from condition (1) and (2), we get

If  then DC bisects the angle
 then DC bisects the angle  . [Proved]

Answer:
c. x = -9.
Step-by-step explanation:
The excluded value is the value of x which gives a value of 0 to the denominator, so that value would be x =  -9. 
 Note: (x - 7) / 0 is undefined.
