Altitude Length
"Find the length of the altitude of a right triangle.The hypotenuse is separated into lengths of 6 and 15"

Anyone can help me with some solving steps? I just don't know how to set it up; I don't get the whole geometric mean thing and how to apply it to these kind of problems

You should run some malware detection software on your machine.
ImPerfectHacker will probably advise when he is online.

What does that have to do with malware?

Is that the complete question? It seems not to make sense.

Hello, xolauren23x!

Find the length of the altitude of a right triangle.
The hypotenuse is separated into lengths of 6 and 15.

Code:

```              C               *             *|  *             * |    *           *  |        *           *  |          *         *    |h            *         *    |                *       *      |                    *     A * - - - * - - - - - - - - - - - * C           6  D          15```

Angle C = 90°.
Altitude h = AD divides the hypotenuse into: AD = 6 and DC = 15.

That geometric mean theorem says: . .= .(6)(15)
. . . . . . . . . . . . . __ . . . . .__
Therefore: .h .= .√90 .= .3√10
