Ten vertical poles of different height standing at equal distances on a straight line, subtend the same angle $\displaystyle 30$° at a point O on the line. If the height of the tallest pole is $\displaystyle 12$ units and the distance of the foot of the shortest pole from O is $\displaystyle 1$ unit, then the distance between two consecutive poles is
Official answer
(1)
$\displaystyle \frac{12 \sqrt{3}-1}{9}$
