Answer:

\huge{\boxed{\red{\bf{\mathfrak{Your\:solution}}}}}

sec¢ = {x}+ \frac{1}{4x}

by squaring

{sec}^2¢ = { {x}+ \frac{1}{4x} }^2

we know that {sec}^2¢ - {tan}^2¢ = 1

so {tan}^2¢ = {sec}^2¢ - 1

{tan}^2¢ = { {x}+ \frac{1}{4x} }^2 - 1

after solving this we get

tan¢ = {x}+ \frac{1}{4x} and {x} - \frac{1}{4x}

putting both values

{x}+ \frac{1}{4x} + {x}+ \frac{1}{4x}

= 1 / 2x

{x}+ \frac{1}{4x} + {x} -  \frac{1}{4x}

= 2x

Answer:

2x

Explanation:

sec a = hypotensus /adjacent , therefore on taking l c m of sec a we get 4x2+1 /4x therefore by pythagorus therom we can find opposite side p2=h2-b2 . subsitute value of h and b then p =4x2-1 ,tan a =p/b =4x2-1/4x. 2 . take Lhs sec a +tana = 4x2 -1 /4x + 4x2+1/4x = 8x2/4x=2x
