Answer 2

Answer:

x = 26.23

Step-by-step explanation:

b) The sum of four exterior angle is always 360 degrees.

∴ (4x - 5) + (5x - 5) + x + (4x + 20) = 360

             4x - 5 + 5x - 5 + 4x + 20  = 360

                                         13x + 10 = 360

                                                 13x = 360 - 10

                                                     x = 350 / 13

                                                  ∴ x = 26.92
