Find the value of x.

Answer:
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
Answer:
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
