Answer 2

$\huge\pink{\underline{\red H\orange e\purple l\blue l\green o}}$

$\huge\orange{\mid{\overline{\underline{\mathfrak{Solution:-}}}}\mid}$

$\large\red{ \tan(30) = \frac{1}{ \sqrt{3} }}$

$\large\blue{ { \tan}^{2} 30 = \frac{1}{3}}$

$\large \frac{1 - {tan}^{2} 30 }{1 + {tan}^{2}30 } = \frac{1 - \frac{1}{3} }{1 + \frac{1}{3} } \\ = \frac{3 - 1}{3 + 1} = \frac{2}{4} = \frac{1 }{2}$
