An "inverted V" antenna is used in areas of limited space as it can significantly reduce the ground footprint of the antenna without significantly impacting performance. Your neighbor is an amateur radio enthusiast who has such an antenna. The antenna is anchored two feet above the ground on the sides and to a 20-foot tall mast 12 feet away. Write the equation that describes this situation, assuming the origin is on the ground beneath the anchor point on the left side of the antenna.
