AI Generated Solution

To solve the problem, we need to prove that the angle of elevation of the top of the tower remains unchanged when both the height of the tower and the distance from the point of observation are increased by 10%. ### Step-by-Step Solution: 1. **Define Variables**: - Let the height of the tower be \( h \). - Let the distance from the point of observation to the foot of the tower be \( x \). - The angle of elevation from the point of observation to the top of the tower is \( \theta_1 \). ...
