 let height of the flagstaff is h    and base distance is k                                                                                                       so for the first case  tan 60 = h/k   and for second case tan y = h / 3k  (base is now 3k)

dividing two eqn. we get tan 60 / tan y = 3 ===> y = 30 degree
