\cos \,\,\theta = - \frac{{\sqrt 3 }}{2}

and

\sin \,\,\alpha = - \frac{3}{5}

, where

\theta

does not lie in the third quadrant, then

\frac{{2\tan \alpha + \sqrt 3 \tan \theta }}{{{{\cot }^2}\theta + \cos \alpha }}

is equal to

View answer and explanation

Correct option: B

\frac{5}{{22}}

Option B (

\frac{5}{{22}}

) is correct because substituting the values of

\tan \alpha

\tan \theta

\cot \theta

, and

\cos \alpha

into the expression and simplifying yields this result.
