If the length of a shadow of a tower is increasing, then the angle of ...
The angle of elevation θ can be expressed as tanθ=length of the shadow/height of the tower.
tanθ will decrease as the length of the shadow increases i.e θ will decrease.
tanθ will decrease as the length of the shadow increases i.e θ will decrease.

If the length of a shadow of a tower is increasing, then the angle of ...
Explanation:
When the length of the shadow of a tower is increasing, it means that the distance between the tower and the tip of the shadow is increasing. This can happen when the angle of elevation of the sun is decreasing.
Angle of Elevation:
The angle of elevation is the angle between the horizontal line and the line of sight from the observer to an object that is above the horizontal line. In this case, the angle of elevation is the angle between the horizontal line and the line of sight from the observer to the top of the tower.
Key Points:
- When the angle of elevation decreases, the line of sight from the observer to the top of the tower becomes more parallel to the ground.
- As a result, the shadow of the tower becomes longer because the distance between the tower and the tip of the shadow increases.
- This can happen when the sun is moving further away from the vertical position and closer to the horizon.
- As the sun moves closer to the horizon, the angle of elevation of the sun decreases.
Conclusion:
Therefore, when the length of a shadow of a tower is increasing, it indicates that the angle of elevation of the sun is decreasing. Hence, the correct answer is option 'B' - decreasing.
