give me right ans plsssssssssssssssss ​

Answer 1

Answer:

$\boxed{\implies\bf \frac{8}{3} }$

Step-by-step explanation:

$\bf \frac{4}{ {tan}^{2} 60 \degree} + \frac{1}{ {cos}^{2} 30\degree} - 2 {sin}^{2}45\degree \\ \\ \implies\bf \: \frac{4}{ { (\sqrt{3}) }^{2} } + \frac{1} { (\frac{ \sqrt{3} }{2})^{2} } - 2( { \frac{1}{ \sqrt{2} } })^{2} \\ \\ \\ \implies\bf \: \frac{4}{3} + \frac{4}{3} - 1 \\ \\ \boxed{\implies\bf \frac{8}{3} }$
