Answer:

50°

Step-by-step explanation:

In a parallelogram, opposing angles must be equal.  Note how 75° = 75°.  Thus, opposing angles 2x + 5 and x + 55 must also be equal.

Solve this equation for x.

Subtracting x from both sides yields x + 5 = 55.  Next:  Subtracting 5 from both sides yields x = 50° (answer choice C)
