A man standing on the ground observes the top of a building at an angle of elevation 45°. If he moves 10 m back and observes the top at an angle of elevation 30°, find the height of the building.
Q1. A man standing on the ground observes the top of a building at an angle of elevation 45°. If he moves 10 m back and observes the top at an angle of elevation 30°, find the height of the building.
Answer: 5(3 + √3) m
Explanation: Using trigonometric ratios for both angles and the given distance, we can form equations to solve for height, yielding 5(3 + √3) m.
