@mathslover what does n axis refer to? this is supposed to be a three dimensional coordinate system

Well the question dont tells this .... I am also confused , also in starting it is written : Treat vertically upward as Kdw:1349109611966:dw

i mean \[\tan \theta = \frac{ 1 }{ \sqrt3 }\]

You're correct @ghazi but HOW?

see if you consider a three dimensional system check out the spherical coordinate system on google you'll find theta is the angle between x and y axis now \[\tan \theta= \frac{ y }{ x }=\frac{ 1 }{ \sqrt3 }\] x and y are the intercepts
