A spherical gas balloon of radius $\displaystyle 16$ meter subtends an angle $\displaystyle 60$° at the eye of the observer A while the angle of elevation of its center from the eye of A is $\displaystyle 75^{\circ}$. Then the height (in meter) of the top most point of the balloon from the level of the observer's eye is :
Official answer
(2)
$\displaystyle 8(\sqrt{6}+\sqrt{2}+2)$
