Transcript text: A vertical tower 132.0 ft high is anchored to the ground by guy wires as shown in the figure. How long (in ft ) is each guy wire? (Round your answers using the rules for working with measurements.)
Solution
Solution Steps
Step 1: Identify the heights and distances for each guy wire
The vertical tower is 132.0 ft high.
The horizontal distances from the base of the tower to the points where the guy wires are anchored are given.
Step 2: Calculate the length of guy wire A
Guy wire A is anchored 100 ft from the base of the tower (25 ft + 50 ft + 25 ft).
Use the Pythagorean theorem: \( A = \sqrt{(132.0)^2 + (100.0)^2} \).
Step 3: Calculate the length of guy wire B
Guy wire B is anchored 75 ft from the base of the tower (25 ft + 50 ft).
Use the Pythagorean theorem: \( B = \sqrt{(132.0)^2 + (75.0)^2} \).
Final Answer
Length of guy wire A: \( \sqrt{(132.0)^2 + (100.0)^2} = \sqrt{17424 + 10000} = \sqrt{27424} \approx 165.6 \) ft
Length of guy wire B: \( \sqrt{(132.0)^2 + (75.0)^2} = \sqrt{17424 + 5625} = \sqrt{23049} \approx 151.8 \) ft
