engineering mathematics MCQ #185

  1. Question 1

    Q1. The angle of depression from the top of a tower to a point on the ground is 30°. If the height of the tower is 20 m, find the distance from the tower to the point.

    • A) 20√3 m
    • B) 20 m
    • C) 20/√3 m
    • D) 40 m

    Answer: 20√3 m

    Explanation: Using tan(30°) = 20 / distance, we have 1/√3 = 20 / distance, so distance = 20√3 m.
