Answer:

C. 140

Step-by-step explanation:

In a parallelogram, opposite angles are congruent (equal), and consecutive angles are supplementary (add up to 180).

12x + 104 + x + 37 = 180

13x + 141 = 180

13x = 39

x = 3

Plug value of x into the x in Angle A.

12 (3) + 104

36 + 104

140

I hope this helps.
