The sum (for all polygons) of the exterior angles are 360. So, 360/11 is 32.72
hope this helps!
Answer:
C. x =(1±i√11)/3
Step-by-step explanation:
Use the quadratic formula to find the solutions.
(−b±√b²−4(ac))/2a
Substitute the values a=3, b=−2, and c=4 into the quadratic formula and solve for x.
2±√(−2)²−4⋅(3⋅4)2⋅3
Simplify.
x=(1±i√11)3
Answer is C or A either one I believe it could be......
