Answer 2

${ \huge{ \red{ \underline{ \mathfrak{ \purple{ÆÑẞWÊR}}}}}}$

Step-by-step explanation:

$= > \frac{5 \cos ^{2} 60^{0} + 4 \sec ^{2} 30 ^{0} - \tan ^{2} 45^{0} }{sin ^{2} 30 ^{0} + \cos ^{2} 30 ^{0}}$

$= > \frac{5( \frac{1}{2})^{2} + 4( \frac{2}{ \sqrt{3} } )^{2} - (1)^{2} }{( \frac{1}{2})^{2} + ( \frac{ \sqrt{3} }{2})^{2} }$

${ \boxed{ \red{ \cos60 = \frac{1}{2} : \sec30 = \frac{2}{ \sqrt{3}}:\tan45 = 1: \sin30 = \frac{1}{2} : \cos30 = \frac{ \sqrt{3} }{2}}}}$

$= > \frac{ \frac{5}{4} + \frac{16}{3} - 1}{ \frac{1}{4} + \frac{3}{4} }$

$= > \frac{ \frac{5}{4} + \frac{16}{3} - 1 }{ \frac{4}{4} }$

$= > \frac{3 + 64}{12}$

$= > { \boxed{ \green{\frac{67}{12}}}}$
