19. find the value of z.<br><br><br><br> PLEASEEEEE HELLPPPPPPP
Dmitriy789 [7]

Answer:

6sqrt(2)

Step-by-step explanation:

You need to use the Right Triangle Altitude Theorem.

There are two parts to this theorem.

Here is the part you need for this problem.

If the altitude is drawn to the hypotenuse of a right triangle, the length of each leg of the right triangle is the geometric mean of the segment of the hypotenuse adjacent to the leg and the entire hypotenuse.

In this case, you end up with this proportion:

Length of leg: z

Length of entire hypotenuse = 8 + 1 = 9

Length of segment of hypotenuse adjacent to leg of interest: 8

8/z = z/9

z^2 = 72

z = sqrt(72)

z = sqrt(36 * 2)

z = 6sqrt(2)

An axiom in Euclidean geometry states that in space, there are at least points that do
oksian1 [2.3K]

An axiom in Euclidean geometry states that in space, there are <u>2</u> points that <u>lie on the same line</u>.

This is called the two-point postulate. According to Euclidean geometry, in space, there are at least two points, and through these points, there exists exactly one line. This means that there is only one single line that could pass between any two points. This is a mathematical truth. It is known as an axiom because an axiom refers to a principle that is accepted as a truth without the need for proof.
