Answer:

here ,

        b = d  and a = c (opposite angles of a parallelogram are equal)

  so, b = 51°

the sum of all angle of a parallelogram = 360

                                           a + b + c + d = 360

                                         x + 51 + x +51  = 360

                                                 2x + 102  = 360

                                                            2x = 360 - 102

                                                            2x = 258

                                                              x = 258/2

                                                              x = 129

so,   a = 129°

       b = 51°

       c = 129°

       d = 51°

option d) is correct 129°
