Plz solve third part asap

Dear student,

Assuming your question to be,

W e h a v e, \tan (2 \times 30 °) = \frac{2 \tan 30 °}{1 - \tan^{2} 30 °} L H S = \tan (2 \times 30 °) = \tan (60 °) = \sqrt{3} R H S = \frac{2 t a n 30 °}{1 - t a n^{2} 30 °} = \frac{2 \times \frac{1}{\sqrt{3}}}{1 - {(\frac{1}{\sqrt{3}})}^{2}} = \frac{\frac{2}{\sqrt{3}}}{\frac{3 - 1}{3}} = \frac{2}{\sqrt{3}} \times \frac{3}{2} = \sqrt{3} T h e r e f o r e, R H S = L H S . H e n c e d o n e!
