HELP ME Which data set has the widest spread?

A.
data set A: 1, 1, 2, 1, 2, 1
B.
data set B: 2, 2, 4, 4, 3, 3
C.
data set C: 1, 1, 2, 2, 1, 5
D.
data set D: 3, 5, 5, 5, 5, 4

data set C.

Step-by-step explanation:

This set has a bigger/wider range (1-5)

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
