Answer:

Height of cliff = 67.92 ft

Step-by-step explanation:

Refer the figure given

      Distance to base of cliff from boat = AB = 128 feet

      Angle of elevation to the top of a cliff = ∠ABC = 27°57'

We need to find height of cliff = AC

We have

       \(tan(27^057')=\frac{AC}{AB}=\frac{AC}{128}\\\\AC=67.92ft\)

Height of cliff = 67.92 ft
