What is the anlge between a vector vec A = 4 hati+3hatj+5hatk and the x-axis ?

What is the angle between two vectors vec P =2hati +3hatj +hatk and vec Q =-3hati +6hatk .

Find the angle between the vectors vec A = hati + hatj + hatk and vec B =-hati - hatj + 2hatk .

The angle between the vector vec(r) = 4 hati + 8 hatj + hatk makes with the x-axis is :
