The location of Avenger's Tower is important to the safety of our planet. Steve, Natasha, and Bruce happen to all live equidistant from each other. Since Tony is filthy rich and can buy whatever he wants, he has decided to place the tower somewhere between their houses. Where in this triangle should the tower be located and why? Geometrically, how could you find this spot? (Assume that no super powers
or tech will assist these 3 Avengers when they travel to the tower)
