Answer 2

Answer:

x= 120°

Step-by-step explanation:

as the sum of all exterior angle of any polygon is 360

∠A + ∠B + ∠C + ∠D = 360

30 +  90 +   x  + x = 360

              120 + 2x = 360

                        2x =360 -120

                        2x = 240

                          x =240/2

                          x = 120°
