Question

plz solve that question ​

Answer 1

$\sec( \alpha ) - \cos( \alpha ) = x \\ \frac{1}{ \cos( \alpha ) } - \cos( \alpha ) = x \\ 1 - { \cos}^{2} \alpha = x \: \cos( \alpha ) \\ { \sin}^{2} \alpha = x \: \cos( \alpha ) \\ \sin( \alpha ) = \sqrt{x \: \cos( \alpha ) }$

Put the value of x and cos alpha to find sin alpha

#NOTE :- I USE ALPHA IN PLACE OF THETA
