Answer:

About 10 feet

Step-by-step explanation:

Since I'm assuming you need to find the height of the supporting wall, I recommend drawing a diagram to help you better visualize what it would look like, like in the attached diagram. You'll see that it forms a triangle, with leg lengths 4.5 and x and a hypotenuse length 11. Use the Pythagorean Theorem to find the height of the supporting wall.

Hope this helps!

Is a ray an undefined term

Tatiana [17]

From these three undefined terms, all other terms in Geometry can be defined. In Geometry, we define a point as a location and no size. A line is defined as something that extends infinitely in either direction but has no width and is one dimensional while a plane extends infinitely in two dimensions.
Hope this helps you !!

A circular fence is being placed around a tree. The diameter of the fence is 4 feet. How much fence is used around the tree? Lea

Step2247 [10]

Answer:

8π

Step-by-step explanation:

If we are given the diameter of this circular fence, then we can solve for the radius. Just take the diameter of 4 and divide by 2 which is 2.

The circumference of a circle is 2πr²

Just plug in the variables and you get 2π(2)² which is 8π

Hope this helps! :)

HELP PLEASE!!

Answer:

Quadrilateral FSHB∼quadrilateral KTWJ.

Step-by-step explanation:

Given two quadrilaterals we have to prove these two similar.

The two quadrilaterals are similar if the corresponding sides of these are proportional then only the quadrilateral are proportional i.e

∴ $\frac{FS}{KT}=\frac{SH}{TW}=\frac{HB}{WJ}=\frac{BF}{JK}$

If the above condition satisfied then the quadrilateral are similar.

Let us find these ratios

$\frac{FS}{KT}=\frac{28}{21}=1.333$

$\frac{SH}{TW}=\frac{24}{18}=1.333$

$\frac{HB}{WJ}=\frac{18}{13.5}1.333$

$\frac{BF}{JK}=\frac{18}{13.5}1.333$

All ratios are equal.

Hence, the corresponding sides and angles of these two quadrilaterals are proportional implies that these two are similar i.e quadrilateral FSHB∼quadrilateral KTWJ.

Katyanochek1 [597]

Answer: B. The data represent a sample since the data are a subset of units.

Step-by-step explanation:

A population is the largest group of entire observations that can be made during a study.
A sample is a finite subset of the population that represents the entire population.

Here,

Population = Participants for the study were those who used a popular social networking Web site.

Since the entire data for the "persons used a popular social networking Web site" is not possible.

There have been taken a sample of them.

∴ Correct answer is B. The data represent a sample since the data are a subset of units.
