Q1. The shadow of a tower is 50 m when the sun's elevation is 30°. What is the height of the tower?
Answer: 50/√3 m
Explanation: The tangent of 30° equals the ratio of the height of the tower to the length of the shadow. Since tan(30°) = 1/√3, rearranging gives the height as 50/√3 m, applying the formula tan(angle) = opposite/adjacent.
