Answer:
Explanation:
Please see attached photo for explanation.
In the attached photo, X is the distance of the swimmer from the cliff.
Thus, we can obtain the value of x by using Tan ratio as illustrated below:
θ = 54.6°
Opposite = 100 foot
Adjacent = x =.?
Tan θ = Opposite /Adjacent
Tan 54.6 = 100/x
Cross multiply
x × Tan 54.6 = 100
Divide both side by Tan 54.6
x = 100 / Tan 54.6
x = 71.07 foot
Therefore, the swimmer is 71.07 foot from the cliff.
