Answer:

$\frac{sin(30 - a)}{cosa - \sqrt{3} sina} = \\ \\ you \: know... \\ sin(x - y) = sinx.cosy - cosx.siny \\ \\ \\ \\ = > \frac{sin30 \times cosa - cos30 \times sina}{cosa - \sqrt{3} sina} \\ \\ \\ = > \frac{ \frac{1}{2} \times cosa - \frac{ \sqrt{3} }{2} \times sina }{cosa - \sqrt{3} sina} \\ \\ \\ \\ = > \frac{1}{2}( \frac{cosa - \sqrt{3} sina}{cosa - \sqrt{3} sina} ) = = > > \frac{1}{2} \: \: ans...$
