engineering mathematics MCQ #15

  1. Question 1

    Q1. From a point on the ground, the angle of elevation of the top of a tower is observed to be 60°. From a point 40 m vertically above the first point of observation, the angle of elevation is 45°. The height of the tower is

    • A) 20(3 + √3) m
    • B) 60 m
    • C) 30 m
    • D) 40 m

    Answer: 20(3 + √3) m

    Explanation: Using the relation between the two angles of elevation, we derive the height of the tower.
