To solve this problem, we can use a simple geometric approach. Given that the laser is shot from a point at ground level to a target on a building 100 km away, we need to determine the height of the building such that the laser beam hits the target.
Assuming the laser beam travels in a straight line, we can use a right triangle to represent the situation:
1. The horizontal distance from the laser to the target is \( 100 \) km (which is \(
