A suspension bridge has two main towers of equal height. A visitor on a tour ship approaching the bridge estimates that the angle of elevation to one of the towers is 25degrees. After sailing 391 ft closer he estimates the angle of elevation to the same tower to be 43degrees. Approximate the height of the tower.

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 2
