Can you please explain why you used Cos Z = Z/R instead of Sin?
As Cos = Adj / Hyp and Sin = Opp / Hyp and in our case Cos would be Cos= H/R.
Please clarify.

Hi Yash,
The angle Z is confined between the vertical axis and R. If We took the angle between the horizontal (90-Z) and R you will be correct.
