Answer:
B. sine; 46.5 feet high
Step-by-step explanation:
In this case, we use trigonometric ratio.
Assuming the horizontal ground, the cable and the height of the cliff forms a triangle,
The cable is the hypotenuse, the height of the cliff is opposite to the angle formed by the cable and the horizontal ground.
Thus; the most appropriate function is sine
Such that;
Sine θ = Opposite/Hypotenuse
Where; θ = 25°, opposite is the height of the cliff and hypotenuse is the cable, 110 ft
Therefore;
Sine 25° = Opp/ 110
Hence;
Opp = 110 ft × sine 25°
= 46.488 ft
= 46.5 ft
Therefore;
The function is Sine, and the height of the cliff is 46.5 ft high
