Question

5sin2 30degree+cos2 45degree-4tan230degree/ 2sin 30degree + cos 30degree +tan 45degree
please answer to this question​

Answer 1

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}

Answer 2

Answer:

10 .61

Step-by-step explanation:

5√3/2+4(0.782)÷ 1+√3/2+1
