Answer 1

$\star\:\:\:\sf\large\underline\blue{Question:-}$

• Evaluate the following.

$\star\:\:\:\sf\large\underline\blue{Answer:-}$

$\sf2 \cos45 \degree \cos60 \degree + 2 \sqrt{3} \sin30 \degree \tan60 \degree - \cos0 \degree$

From the T-Ratio table, we will evaluate this. So, we get,

$\sf2 \times \frac{1}{ \sqrt{2} } \times \frac{1}{2} + 2 \sqrt{3} \times \sqrt{3} - 1$

$\sf= \frac{1}{\sqrt{2} } + 3 - 1$

$\sf= 2 + \frac{ \sqrt{2} }{2}$

$\sf = \frac{4 + \sqrt{2} }{2}$

Hence, the required answer is

$\boxed{ \sf = \frac{4 + \sqrt{2} }{2} }$
