Answer:

x = 116°

Step-by-step explanation:

Finding the value of 'x' in a polygon

 [tex]\sf \boxed{\text{Sum of interior angles of a polygon = (n - 2)*180}}[/tex]

                                                           = (5 - 2) *180

                                                           = 3*180

                                                            = 540°

                      90 + 119 + 86 + 129 +x = 540  

                                               424 + x = 540

                                                         x = 540 - 424

                                                         x   = 116°
