MCQ
If ${\rm{cosec }}A + \cot A = \frac{{11}}{2},$ then $\tan A = $
  • A
    $\frac{{21}}{{22}}$
  • B
    $\frac{{15}}{{16}}$
  • $\frac{{44}}{{117}}$
  • D
    $\frac{{117}}{{43}}$

Answer

Correct option: C.
$\frac{{44}}{{117}}$
c
(c) ${\rm{cosec}}\,A + \cot A = \frac{{11}}{2} $

$\Rightarrow {\rm{cosec}}\,A - \cot A = \frac{2}{{11}}$

Therefore $2\cot\, A = \frac{{117}}{{22}} $

$\Rightarrow \tan A = \frac{{44}}{{117}}$.
