Answer 1

$\huge \fbox \green{Solution ✧}$

$\frac{5 cos²60 + 4 sec² 30 - tan² 30}{sin² 30 + cos² 30} \\ \\ \fbox\pink{using the values} \\ \\ = \frac{5 \times( \frac{ {1} }{2} )^{2} + 4 \times (\frac{ {2} }{ \sqrt{3} } )^{2} - ( \frac{1}{ \sqrt{3} } )^{2}}{ (\frac{1}{2}) {}^{2} + (\frac{ \sqrt{3} }{2}) {}^{2} } \\ \\ = \frac{5 \times \frac{1}{4} + 4 \times \frac{4}{3} - \frac{1}{3} }{ \frac{1}{4} + \frac{3}{4}} \\ \\ = \frac{ \frac{5}{4} + \frac{16}{3} - \frac{1}{3} }{ \cancel{\frac{4}{4} }} \\ \\ = \frac{ \frac{5}{4} + \frac{15}{3} }{1} \\ \\ = \frac{15 + 60}{12} \\ \\ = \frac{75}{12}$
