engineering mathematics MCQ #182

  1. Question 1

    Q1. If the angle of elevation of the top of a building from a point on the ground is 30° and the distance from the point to the building is 40 m, find the height of the building.

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

    Answer: 40/√3 m

    Explanation: Using tan(30°) = height / 40, we have 1/√3 = height / 40, so height = 40/√3 m.
