find the value of x by using the Geometric Mean (Altitude) Theorem.
find the value of x by using the Geometric Mean (Altitude) Theory:

Step-by-step solution-:

By using the Geometric Mean (Altitude) Theorem:

find the value of x by using the Geometric Mean (Altitude) Theorem.
The length of the altitude from the right angle to the hypotenuse in a right triangle is the geometric mean of the lengths of segments the altitude divides the hypotenuse into.
(CD)^2=AD\times{DB}

Substitute the CD=12, AD=x, and DB=16 into the Geometric Mean (Altitude) Theorem:

\textcolor{primary}{12^{2}}=\textcolor{secondary}{x}\cdot \textcolor{tertiary}{16}\implies144=16x

After solving:

16x=144\implies x=\frac{\cancel{144}}{\cancel{16}}=9

The value of x is 9:
