Question

A plane rises from​ take-off and flies at an angle of 4 degrees with the horizontal runway. When it has gained 450 ​feet, find the​ distance, to the nearest​ foot, the plane has flown.

Answer 1

To find the distance the plane has flown, you can use trigonometry. The vertical displacement (gain in height) is 450 feet, and the angle of 4 degrees is given. You can use the tangent function: distance = vertical displacement / tangent(angle). Calculate the tangent of 4 degrees, then use that to find the distance.
