Consider the vector

A = 4.10i + 1.60j + 5.40k.

The magnitude of Vector A is 6.97. What are the minimal angles the Vector A makes with the x,y, and z axes?

1 answer

the direction cosines are 4.1/6.97, 1.60/6.97, 5.40/6.97
so, the angle θ with the x-axis is
cosθ = 0.588
θ = 53.97°
do y and z similarly
