Answer 2

Answer:

Step-by-step explanation:

$sin60^{0} = \frac{\sqrt{3} }{2}$

$cos30^{0} = \frac{\sqrt{3} }{2}$

$cot60^{0} = \frac{1}{\sqrt{3} }$

Now,

$sin60^{0}$ + $cos30^{0}$ + $cot60^{0}$ = $\frac{\sqrt{3} }{2}$ + $\frac{\sqrt{3} }{2}$ + $\frac{1}{\sqrt{3} }$

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

                                     = $\sqrt{3}$ + $\frac{1}{\sqrt{3} }$

                                     = $\frac{4}{\sqrt{3} }$

Answer is $\frac{4}{\sqrt{3} }$.
