Answer:

4.72 in.

Step-by-step explanation:

BC = 3.1 in.

CD = 7.2 in.

Altitude of right triangle altitude is given as [tex] h = \sqrt{xy} [/tex], where:

h = altitude

x = 3.1 in.

y = 7.2 in.

Plug in the values into the formula

[tex] h = \sqrt{3.1*7.2} [/tex]

[tex] h = \sqrt{22.32} [/tex]

[tex] h = 4.72 in. [/tex] (nearest hundred)

Answer:

4.72

Step-by-step explanation:
