  1. Question 1

    Q1. A vertical tower stands on a horizontal plane and is surmounted by a vertical flagstaff of height 6 m. At a point on the plane, the angle of elevation of the bottom and top of the flagstaff are 30° and 45° respectively. The height of the tower is

    • A) 3(√3 + 1) m
    • B) 8.196 m
    • C) 9 m
    • D) 3 m

    Answer: 8.196 m

    Explanation: Using trigonometric relations for the angles of elevation, we derive the height of the tower.
