Answer:
147 floors
Step-by-step explanation:
To determine the number of floors in the Burj Khalifa, we can use the information provided. We know that Andre stood 1000 meters away from the building and looked up at a 39.62-degree angle using a laser rangefinder. Let's calculate the height of the Burj Khalifa using basic trigonometry.
First, we can find the height of the building using the tangent function:
tan(angle) = height / distance
tan(39.62 degrees) = height / 1000 meters
height = tan(39.62 degrees) * 1000 meters
height ≈ 747.97 meters
Now, let's calculate the number of floors in the Burj Khalifa. We are given that each floor is 5.079 meters tall.
Number of floors = height / height of each floor
Number of floors = 747.97 meters / 5.079 meters
Number of floors ≈ 147.23 floors
Since we cannot have fractional floors, we can round the number down to the nearest whole number.
Therefore, there are approximately 147 floors in the Burj Khalifa.
