arlik [135]3 years ago

Answer:

138

Step-by-step explanation:

G + H = 180   {G, H are linear pair}

12x + 6 + 4x - 2 = 180

12x + 4x + 6 - 2  = 180

       16x  + 4      = 180

                    16x = 180 - 4

                   16x = 176

                      x = 176/16

                      x = 11

G = 12x + 6

   = 12*11 + 6

  = 132 + 6

  = 138
