Q1. A building casts a shadow of 20 m when the sun's angle of elevation is 60°. What is the height of the building?
Answer: 20√3 m
Explanation: The tangent of 60° equals the ratio of the building's height to the shadow's length. Since tan(60°) = √3, the height is 20 * √3 = 20√3 m, applying the formula tan(angle) = opposite/adjacent.
