Explanation:
The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.
This can be represented as:
![h = √((xy))](https://img.qammunity.org/2021/formulas/mathematics/high-school/loso6wlrpc88tza45cpzri7kq904zx4vm7.png)
Where,
h = the length of the altitude,
x and y are the lengths of the 2 segments formed.
Therefore, the length of the altitude =
