thanks in advance.

Answer 1

Since in a parallelogram the opposite angles are equal and the sum of any two adjacent angle is 180 degrees therefore,

              angleQ + angleR = 180 degrees

         => angleQ = 130 degrees.

angleP = 50 degrees.

angleM = 50 degrees

angleS = angleQ = 130 degrees.

please don't hesitate to ask if you need any more explanation about this question.

Answer 2

Q = S = 130

M = P = 50
