Answer
$B = C \lt A$
Work Step by Step
$A_x = 4$
$A_y = 4$
$B_x = -1$
$B_y = 3$
$C_x = 1$
$C_y = -3$
We can find the magnitude of each vector:
The magnitude of vector A is $\sqrt{(4)^2+(4)^2}$ which is 5.66
The magnitude of vector B is $\sqrt{(-1)^2+(3)^2}$ which is 3.16
The magnitude of vector C is $\sqrt{(1)^2+(-3)^2}$ which is 3.16
We can rank the vectors in order of increasing magnitude:
$B = C \lt A$
