    Answer:

    The parasailor height is 47ft

    Step-by-step explanation:

    We can think of the problem as a right triangle, the string would be the hypotenuse and the height of the parasailor would be a leg.

    well to start we have to know the relationship between angles, legs and the hypotenuse

    α = 36°

    a: adjacent

    o: opposite  = ?

    h: hypotenuse  = 80ft

    sin α = o/h

    cos α= a/h

    tan α = o/a

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

    is the sine

    sin α = o/h

    sin 36° = o/80

    sin 36° * 80 = o

    47.02 = o

    if we round to the nearest tenth

    47.02 = 47.0

    The parasailor height is 47ft
