If `cosx=tany ,cosy=tanz ,cosz=tanx ,` then the value of `sinx` is (a)`2cos18^0` (b) `cos18^0` (c) `sin18^0` (d) `2sin18^0`

Explanation

To solve the problem, we are given the equations:

1. \( \cos x = \tan y \)
2. \( \cos y = \tan z \)
3. \( \cos z = \tan x \)

We need to find the value of \( \sin x \).
