Some Applications of Trigonometry Quiz Some Applications of Trigonometry Quiz for class 10 1 / 7 1. From the top of a 7m high building, the angle of elevation of the top of a cable tower is 60˚ and the angle of depression of its foot is 45˚. The height of the tower in metre is 7(√3 + 1) 7(√3 - 1) 7 - √3 7 + √3 2 / 7 2. The height of the tower is 50√3 50/√3 50 + √3 50 - √3 3 / 7 3. A plane is observed to be approaching the airport. It is at a distance of 12 km from the point of observation and makes an angle of elevation of 60°. The height above the ground of the plane is 6√3 m 4√3 m 3√3 m 2√3 m 4 / 7 4. The shadow of a tower is equal to its height at 10:45 a.m. The sun’s altitude is 30° 60° 90° 45° 5 / 7 5.
