Suppose a 6-ft person wishes to determine the height of a bridge above the bottom of a canyon, as shown in Figure 7.51.

Figure  7.51

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.
a. Identify the two triangles.
b. Are the triangles similar? Why or why not?

c. Find the distance to the bottom of the canyon, if |AP| = 10 ft and |PB| = 40 ft.
