Answer 2

$\bold \red{sec \alpha = \frac{5}{4} } \\ therefore \\ \bold \green{tan \alpha = \frac{3}{4} } \\ now \: according \: to \: given \\ \bold \green{ = } \bold \green{ \frac{1 - \tan( \alpha ) }{1 + \tan( \alpha ) } } \\ = \frac{1 - \frac{3}{4} }{1 + \frac{3}{4} } \\ = \frac{ \frac{1}{4} }{ \frac{7}{4} } \\ = \bold \green{ \frac{1}{7}} \: \: \bold \red{ans} \\ \\ \bold \pink{till \: then \: be \: happy}$
