Suppose a 6- ft person wishes to determine the height of a foot-bridge connecting two buildings, as shown in Figure 7.52.
To do this, this person stands at one end of the bridge (point S) and looks down to a point directly below the other end (point T) that is, to point B. With the help of a companion, point P is determined to form two triangles.
a. Identify the two triangles.
b. Are the triangles similar? Why or why not?
c. Find the height of the footbridge, if
