Answer 1

Step-by-step explanation:

$\frac{5 \: { \sin(30) }^{2} + { \sin(45) }^{2} - 4 \: { \tan(30) }^{2} }{2 \: \sin(30) \cos(30) + \cot(45) }$

$\frac{5 \times \frac{1}{4} + \frac{1}{2} - 12 }{ \frac{ \sqrt{3} }{2} + 1 }$

$\frac{ \frac{5}{4} - \frac{23}{2} }{ \frac{ \sqrt{3} }{2} + 1}$

$\frac{ \frac{5}{4} - \frac{46}{4} }{ \frac{ \sqrt{3 + 2} }{2} }$

$\frac{ \frac{41}{4} }{ \frac{ \sqrt{3} + 2}{2} }$

$\frac{41 + 2 \sqrt{3} + 4 }{4}$

$\frac{45 + 2 \sqrt{3} }{4}$
