PolarNik [594]

Answer:

C. 130

Step-by-step explanation:

Since the sum of the interior angles for a quadrilateral shape is 360 degrees, you take 55 and 45 away from 360 to get 260. You need to then divide that number by 2 to get Q and S, but you are looking for Q in this case, so the answer is 130.
