A flagstaff stands on the top of a building From a point on the ground 15 m away the elevations at the top of the building and the flagstaff are 45∘ and 60∘ respectively the length of the flagstaff is 15(√3−1)m15(√3)m15(√3+1)m15 m

A flagstaff stands on the top of a building From a point on the ground $15 m$ away the elevations at the top of the building and the flagstaff are $45^{\circ}$ and $60^{\circ}$ respectively the length of the flagstaff is
$15 (\sqrt{3} - 1) m$
$15 (\sqrt{3}) m$
$15 (\sqrt{3} + 1) m$
$15 m$
