The angle between the line of sight and the horizontal is 45°. If the height of the observer is 1.7 m and the height of the object is 11.7 m, find the distance between the observer and the object.
Q1. The angle between the line of sight and the horizontal is 45°. If the height of the observer is 1.7 m and the height of the object is 11.7 m, find the distance between the observer and the object.
Answer: 10 m
Explanation: The height difference is 11.7 - 1.7 = 10 m. Using tan(45°) = 10 / distance, we get distance = 10 m.
