For the vectors u and v with magnitudes u = 88 and v = 99, find the angle θ between u and v which makes u and v = 77.

Step-by-step explanation:

Using the vector formula

|u| = magnitude of vector u

|v| = magnitude of vector v

u.v is the dot product of vector u and v

Given |u| = 88, |v| = 99 and u.v = 77, to get we will substitute the given values into the equation above;
