Answer 1

A=Axi^+Ayj^+Azk^

then, the angles which it makes with coordinate axes are given by:

cosθ=Amagnitude of component along concerned direction

where A is the magnitude of A is A=32+62+22=7

therefore, angle with x- axis α=cos−173

                 angle with y-axix β=cos−176  

                 angle with z-axis γ=cos−172
