Answer:
exterior ∠ A = 57°
Explanation:
the sum of the exterior angles of a polygon = 360°
sum the 5 exterior angles and equate to 360
6x - 3 + 4x + 8 + 49 + 3x + 30 + 14x + 6 = 360 , that is
27x + 90 = 360 ( subtract 90 from both sides )
27x = 270 ( divide both sides by 27 )
x = 10
Then
exterior ∠ A = 6x - 3 = 6(10) - 3 = 60 - 3 = 57°
