Answer:
Step-by-step explanation:
\text{The value of given expression is}\frac{55}{6}
Step-by-step explanation:
We have to evaluate the given expression
\frac{5sin^230^{\circ}+cos^245^{\circ}+4tan^{2}60^{\circ}}{2sin30^{\circ}cos60^{\circ}+tan45^{\circ}}
⇒ \frac{5(\frac{1}{2})^2+(\frac{1}{\sqrt2})^2+4(\sqrt3)^2}{(2\times \frac{1}{2}\times \frac{1}{2})+1}
⇒ \frac{\frac{5}{4}+\frac{1}{2}+12}{\frac{1}{2}+1}
⇒ \frac{\frac{55}{4}}{\frac{3}{2}}
⇒\frac{55}{6}
