Answer:

Step-by-step explanation:

1) 97 + x = 64 + 27          {Exterior angle property}

    97 + x = 91

            x = 91 - 97

          x = -6

2) 4x + 17 + 80 + x + 23 = 180   {Angle sum property of triangle}

 4x + x + 17 +80 + 23 = 180

                 5x + 140   = 180

                             5x = 180 - 140

                              5x = 40

                                 x = 40/5

                                x = 8
