Find the value of x.

  x = 12

Step-by-step explanation:

The sum of the exterior angles of a convex polygon is 360°.

  (5x +4)° +(4x +9)° +(9x -6)° +(4x +1)° +(7x +4)° = 360°

  29x +12 = 360 . . . . . divide by °, collect terms

  29x = 348 . . . . . . . subtract 12

  x = 12 . . . . . . . . . divide by 29

x=11.58

Step-by-step explanation:

The sum of an exterior angle of a polygon is 360°,

9x-6+4x+9+5x+4+7x+4+4x+1=360°

29x+24=360

29x=360-24

29x=336

x=336/29

x= 11.586

x=11.58
