Answer:
1609 ft
Step-by-step explanation:
First, we place the given angle in the diagram.
Since it is an angle of elevation, it means the person is looking upwards and the angle will be at point C as shown in the diagram below:
Since we are to determine the horizontal distance from the person to a point on the ground directly below the balloon, it means we are to find the distance BC in the diagram.
By trigonometric ratios:
Therefore, to the nearest foot:
Horizontal Distance = 1609 ft.
