Suppose a 6-ft person wishes to determine the height of a bridge above the bottom of a canyon, as shown in the figure below. To do this, this person stands at one end of the bridge (point A) and looks down to a point directly below the other end (point B). With the help of a companion, point P is determined to form two triangles. Find the distance to the bottom of the canyon, if
