Math Problem Statement

A pole 8 feet tall is used to support a guy wire for a tower, which runs from the tower to a metal stake in the ground. After placing the pole, Mav measures the distance from the pole to the stake and from the pole to the tower, as shown in the diagram. Find the length of the guy wire, to the nearest foot.

Solution

To solve this problem, we need to calculate the length of the guy wire, which forms the hypotenuse of the triangle shown in the diagram.

Step 1: Triangle dimensions

From the diagram:

  • The vertical height is 8 feet.
  • The horizontal base is 24 feet + 3 feet = 27 feet.

Step 2: Apply the Pythagorean theorem

The length of the guy wire cc can be found using: c=a2+b2c = \sqrt{a^2 + b^2} where:

  • a=8a = 8 feet (vertical side),
  • b=27b = 27 feet (horizontal side).

Step 3: Compute the length

c=82+272c = \sqrt{8^2 + 27^2} c=64+729c = \sqrt{64 + 729} c=793c = \sqrt{793} c28.14 feet.c \approx 28.14 \text{ feet}.

Final Answer:

The length of the guy wire is approximately 28 feet.

Let me know if you'd like a detailed breakdown of these steps or any related questions. Here are five questions to consider expanding upon this problem:

  1. How would the calculation change if the height of the pole was different?
  2. What if the distances were measured in different units (e.g., meters)?
  3. How is the Pythagorean theorem applied in real-world situations like this?
  4. Could you calculate the angle between the wire and the ground?
  5. How would wind tension affect the design of the guy wire?

Tip: For solving triangle-related problems, always identify whether the Pythagorean theorem or trigonometric ratios are appropriate for your calculation.
