Solution Steps

Step 1: Calculate sin⁡(76∘) \sin(76^{\circ})

To find the length of the guy wire, we first need to calculate sin⁡(76∘) \sin(76^{\circ}) . The value obtained is: sin⁡(76∘)≈0.9703 \sin(76^{\circ}) \approx 0.9703

Step 2: Use the Sine Function to Find the Length of the Wire

Using the sine function, we can relate the height of the tower to the length of the wire. The formula is given by: hypotenuse=oppositesin⁡(θ) \text{hypotenuse} = \frac{\text{opposite}}{\sin(\theta)} Substituting the known values: hypotenuse=128sin⁡(76∘)≈1280.9703≈131.92 \text{hypotenuse} = \frac{128}{\sin(76^{\circ})} \approx \frac{128}{0.9703} \approx 131.92

Final Answer

The length of the wire is approximately: 131.92 feet \boxed{131.92 \text{ feet}}
