To find the height of the tower, we can use trigonometry, specifically the sine function, since we have the angle the wire makes with the ground (70°) and the length of the wire (471 feet). The sine of an angle in a right triangle is equal to the opposite side (height of the tower, in this case) divided by the hypotenuse (the length of the guy wire). Therefore, we can set up the equation:sin(70°) = height / 471Solving for the height gives:height = 471 * sin(70°)Using a calculator, we find:height ≈ 471 * 0.93969 ≈ 442.5 feetHowever, since this option is not available and considering the distance from the point where the wire is attached to the ground to the tower is 218 feet, which is not directly related to the calculation of the height using the sine function, it seems there might have been a misunderstanding in the interpretation of the given information. Given the options and the correct approach to use the sine function for the height calculation:height ≈ 471 * sin(70°) ≈ 442.5 feetThe correct answer should be based on the sine calculation, but since my calculation does not match any of the provided options and considering potential rounding or calculation differences, the closest match to the calculated height is:B) 446.2 ftThis suggests there might have been a slight miscalculation or rounding difference in the original question or answer choices.
