Question

plz help me to find out this answer​

Answer 1

Answer:

$\frac{324}{14}$

Step-by-step explanation:

FOR THIS WE MUST KNOW SOME VALUES

$\sin(30) = \frac{1}{2}$

$\cos(45) = \frac{1}{ \sqrt{2} }$

$\tan(60) = \sqrt{3}$

$\cos(60) = \frac{1}{2}$

$\tan(30) = \frac{1}{ \sqrt{3} }$

$\cot(60) = \frac{1}{ \sqrt{3} }$

LET US SUBSTITUTE

$\frac{5 { (\frac{1}{2} )}^{2} + { (\frac{1}{ \sqrt{2} }) }^{2} + 4 { (\sqrt{3}) }^{2} }{2 { (\frac{1}{2}) }^{2} \times \frac{1}{2} + \frac{1}{ \sqrt{3} } \times \frac{1}{ \sqrt{3} } }$

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

$\frac{ \frac{5}{4} + \frac{1}{2} + 12 }{ \frac{2}{8} + \frac{1}{3} }$

$\frac{ \frac{5 + 1(2) + 12(4)}{4} }{ \frac{2(3) + 1(8)}{24} }$

$\frac{ \frac{5 + 1 + 48}{4} }{ \frac{6 + 8}{ 24} }$

$\frac{ \frac{54}{4} }{ \frac{14}{24} }$

$\frac{54 \times 6}{14}$

$\frac{324}{14}$
