Question:medium
When the Sun ray's inclination increases from 30 degrees to 60 degrees, the length of the shadow of a tower decreases by 60 m. Find the height of the tower.
When the Sun ray's inclination increases from 30 degrees to 60 degrees, the length of the shadow of a tower decreases by 60 m. Find the height of the tower.
Show Hint
Shadow length equals height divided by the tangent of the elevation angle; subtract the two shadow lengths.

- 50.9 m
- 51.96 m
- 48.8 m
- None of these
Show Solution
The Correct Option is B
Solution and Explanation
Using tan30=0.5774, tan60=1.7321: s1=1.7321h, s2=0.5774h. Diff=1.1547h=60 => h=51.96m.
Final Answer: 51.96 m, option (2).
Final Answer: 51.96 m, option (2).
