A square, of each side $\displaystyle 2$, lies above the $\displaystyle x$-axis and has one vertex at the origin. If one of the sides passing through the origin makes an angle $\displaystyle 30$° with the positive direction of the $\displaystyle x$-axis, then the sum of the $\displaystyle x$-coordinates of the vertices of the square is :
Official answer
(2)
$\displaystyle 2 \sqrt{3}-2$
