Question:

Is cos x = $\frac{5}{13}$, then what is the value of tanx + cot x ?

Options:

$\frac{169}{109}$

$\frac{169}{60}$

$\frac{109}{169}$

$\frac{60}{169}$

Correct Answer:

$\frac{169}{60}$

Explanation:

We are given that ,

cos x = \(\frac{5}{13}\)

{ we know, cos A = \(\frac{B}{H}\) }

By using pythagoras theorem ,

P² + B² = H²

P² + 5² = 13²

P = 12

Now,

tanx + cotx

= \(\frac{12}{5}\) + \(\frac{5}{12}\)

= \(\frac{169}{60}\)
