10. The upper `3/4` portion of a vertical pole subtends an angle `tan^-1(3/5)` at the point in the horizontal plane through its foot. The tangent of the angle subtended by the pole at the same point is

The upper (3/4)^(th) portion of a vertical pole subtends an angle "tan"^(-1)3/5 at a point in the horizontal plane through its foot at a distance 40 m from the foot . A possible height of the vertical pole is

The upper (3)/(4) th portion of a vertical pole subtends an angle theta such that tan theta=(3)/(5) at a point in the horizontal plane through its foot and at a distance 40m from the foot.Find the possible height of the vertical pole.

If a flag staff subtends the same angles at the points A,B,C and D on the horizontal plane through its foot, the points A,B,C and D from a
