Answer 2

Answer:

55/6

Step-by-step explanation:

sin30 = 1/2

cos45 = 1/√2

tan60 = √3

cos60 = 1/2

tan45 = 1

Now, substituting these values in equation

we get,

$\frac{5\times (\frac{1}{2})^2 + (\frac{1}{\sqrt2})^2 + 4 \times (\sqrt3)^2}{2(\frac{1}{2})(\frac{1}{2}) + 1} \\\\\implies \frac{\frac{5}{4}+ \frac{1}{2}+ 12}{\frac{3}{2}} \\\\\implies \frac{\frac{5+2+48}{4}}{\frac{3}{2}} \\\\\implies \frac{55}{6}$

Hope it helps
