A tower T is observed from two points A and B which are 240 metres apart. The angle TAB is found to be 57degree and the angle TBA is 78degree. Find the distance of the tower from A.

  • Maths -

    You say angle TBA = 78┬░
    This is only possible if A and B are on opposite sides of the tower.
    Confirm this before I solve it.

  • Maths -
