Let the vectors be **u** and **v**
Compute the dot product: **u · v**
Compute the magnitudes: **|u|** and **|v|**
Use the formula: **cos θ = (u · v) / (|u||v|)**
Find the angle: **θ = arccos((u · v) / (|u||v|))**
Ensure neither vector is the zero vector
If needed, convert the result from radians to degrees
