  1. Question 1

    Q1. The upper 3/4th portion of a vertical pole subtends an angle tan^-1(3/5) at a point in the horizontal plane through its foot and at a distance 40 m from the foot. The height of the pole is

    • A) 40 m
    • B) 45 m
    • C) 50 m
    • D) 60 m

    Answer: 45 m

    Explanation: Using the tangent of the angle subtended by the upper portion, we derive the height of the pole.
