Step-by-step explanation:

We know that

sin (30°) = 1/2

tan (60°) = √3

cos(60°) = 1/2

sec(30°) = 2/√3

Now putting the values;

$2 \times(\frac{1}{2})^2 \times\sqrt{3} - [3\times(\frac{1}{2})^2\times(\frac{2}{\sqrt{3} }) ^2]\\\\2\times\frac{1}{4} \times\sqrt{3} - [3\times\frac{1}{4}\times\frac{4}{3}]\\\\\\\frac{\sqrt{3} }{2} -1\\\\ \frac{\sqrt{3}-2 }{2}$
