Question

compute the angle between the force vector F and the z axis.

heeeeelp!!

Answer 1

the x and y here does not form 90 degrees angle

Answer 2

i mean y and z rather

Answer 3

i know what you mean but the figure isnt like that.
tnx for replying though :)

Answer 4

got it

Answer 5

If α,β,γ are the angles made by a vector with the coordinate axes. Then we have a result\[\cos ^{2} \alpha + \cos ^{2} \beta + \cos ^{2}\gamma = 1\]

Let α=50
β =60

Substitute in the above and find γ,the angle made with the z axis.
