    Answer:

    The angle of descent is 81°

    Step-by-step explanation:

    We have to think of the problem as a right triangle where the height of the plane is the leg adjacent to the angle of descent and the distance from the ground is the opposite leg

    well to start we have to know the relationship between angles, legs and the hypotenuse in a right triangle

    α = ?

    a: adjacent  = 10,000ft

    o: opposite  = 60,000

    h: hypotenuse

    sin α = o/h

    cos α = a/h

    tan α = o/a

    we see that it has (angle, adjacent, opposite)

    is the tangent

    tan α = o/a

    tan α = 60,000/10,000

    tan α = 6

    α = tan^-1(6)

    α = 80.5377

    if we want to round to the nearest degree

    α = 80.5377° = 81°

    The angle of descent is 81°
