Answer:

The length of the rope is 7.6 ft ( approx )

Step-by-step explanation:

Let, The line segment AB shows the length of the pole, ( where A is the top and B is the bottom ) and line segment AC shows the rope,

According to the question,

AB = 3.5 ft,

BC = 6.8 ft,

Since, the pole must be vertical with respect to the ground,

That is, ∠ABC = 90°,

Thus, by Pythagoras theorem,

AC² = AB² + BC²

⇒ AC² = 3.5² + 6.8² = 12.25 + 46.24 = 58.49,

⇒ AC = √ 58.49 = 7.64787552 ≈ 7.6 ft

Hence, the length of the rope is approximately 7.6 ft.
