Answer:

  16.2

Step-by-step explanation:

You want the length of CB in the triangle shown, given AB=9 and BD=5.

Similar triangles

The ratio of corresponding sides is the same for any pair of these similar triangles:

  CB/AB = AB/BD . . . . . . . . . . . . . hypotenuse/short side

  CB = AB²/BD = 9²/5 = 16.2

The length of CB is 16.2 units.
