  • Two flagstaffs stand on a horizontal plane. A and B are two points on the line joining their feet and between them. The angles of elevation of the tops of the flagstatts as seen from A are 30^(@) and 60^(@) and as seen from B are 60^(@) and 45^(@). If AB=30 , then the distance between the flagstaffs in motres is:

    A
    `30 + 15 sqrt3`
    B
    `30 - 15 sqrt3`
    C
    `60 + 15 sqrt3`
    D
    `60-15 sqrt3.`
