- Multiply x-1 on both sides

Now
ATQ to the equation
x should be greater than 1 .Because if it becomes 1 then the denominator will be 0 which is impossible.
Hence x>1
Thus
![\\ \sf{:}\!\implies 1](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%7B%3A%7D%5C%21%5Cimplies%201%3Cx%3C%5Cdfrac%7B5%7D%7B4%7D)
Now

Answer:
steps
Step-by-step explanation:
1 - sin²θ / (1 - cosθ) = 1 - (1 - cos²θ) /(1 - cosθ)
= 1 - (1 + cosθ)(1 - cosθ) /(1 - cosθ)
= 1 - (1 + cosθ)
= - cosθ
