An airplane pilot over the Pacific sights an atoll at an angle of depression of 7°
At this time, the horizontal distance from the airplane to the atoll is 3,729 meters.
3,667 meters
458 meters
3,701 meters
454 meters
The correct answer is 3,701 meters.
To find the horizontal distance from the airplane to the atoll, we can use trigonometry.
Let x be the horizontal distance.
tan(7°) = height of atoll / x
tan(7°) = 454 / x
x = 454 / tan(7°)
x ≈ 3,701 meters
Therefore, the horizontal distance from the airplane to the atoll is approximately 3,701 meters.
