Answer:

get your formula, find the vectors, get the length of each vector, calculate the dot product by using the dot product formula: a x b = |a| |b| cos θ.

we know that

The cosine of the angle between two vectors is equal to the dot product of this vectors divided by the product of vector magnitude.

so

see the attached image

then

when you have cosine of angle theta

theta=arcos(theta) -----> using a calculator
