A 25-foot wire is stretched from the top of a pole to a stake on the ground. If the stake is 7 feet from the base of the pole, how tall is the pole?
✓ Correct Answer: Option C
This forms a right triangle. Use the Pythagorean theorem: a² + b² = c². Let the pole height be 'a'. So, a² + 7² = 25². a² + 49 = 625. a² = 576. a = √576 = 24 feet.
