I have two vectors(adsbygoogle = window.adsbygoogle || []).push({});

Vector A and B

Axi = -3

Ayj = 5.4

Bxi = 1.3

Byj = -3.9

I want the angle between them so I do the dot product

(-3)(1.3)+(5.4)(-3.9) = -24.96

Therefore the angle between them is

-24.96 = |-24.96|cos(theta)

Arccos(-24.96/24.96) = theta

Arccos(-1) = theta

Theta = pi = 180 degrees.

Is this correct?
