Question

what is solution equation

Answer 1

Here is your answer :

(2/√3)/{1+(1/√3)^2}

= (2/√3)/{1+(1/3)}

= (2/√3)/{4/3}

= (√3)/2

Answer 2

$given \\ \\ = \frac{2 \tan(30 {}^{0} ) }{1 + { \tan(30 {}^{0} ) }^{2} } \\ \\ = \frac{2 (\frac{1}{ \sqrt{3} } ) }{1 + ( \frac{1}{ \sqrt{3} } ) {}^{2} } \\ \\ = \frac{\frac{2}{ \sqrt{3} } }{ \frac{4}{3} } \\ \\ = \frac{2}{ \sqrt{3} } \times \frac{3}{4} \\ \\ = \frac{1}{2} \times \frac{ \sqrt{3} }{1} \\ \\ = \frac{ \sqrt{3} }{2} \\ \\ hope \: this \: helps \: you$
