What is the angle between `(vecP+vecQ)` and `(vecPxxvecQ)`

What can be the angle between vecP+vecQ and vecP-vecQ ?

Two vectors vecP and vecQ are having their magnitudes in the ratio sqrt(3) :1. Further । vecP+vecQ । =। vecP - vecQ। then the angle between the vectors (vecP+ vecQ) and (vecP - vecQ) is
