Answer:

(b) Mark the intersection points of the arcs, and draw a line through those two points.

Step-by-step explanation:

Obviously, the last step in bisecting a line segment is to draw the line or point that cuts the line segment into two equal parts. The step describing the drawing of such a segment is ...

Mark the intersection points of the arcs, and draw a line through those two points.

<em>Additional comment</em>

You would do well to perform these steps with a real compass and straightedge on a real piece of paper. The physical act will help you remember <em>how</em> it works and what the steps are. Perhaps it will even help you understand <em>why</em> it works.

A community pool that is shaped like a regular pentagon needs a new cover for the winter months. The radius of the pool is 20.10

boyakko [2]

Answer:

$960.42\text{ ft}^2$

Step-by-step explanation:

Please find the attachment.

We have been given that a community pool that is shaped like a regular pentagon needs a new cover for the winter months.

To find the area of community pool we will use area of pentagon formula.

$\text{Area of pentagon}=\frac{1}{2}a*p$ , where, a represents the apothem or perpendicular distance from the center of the pentagon and p represents perimeter of pentagon.

Let us find the perimeter of our given pentagon by multiplying each side length by 5.

$\text{Perimeter of community pool}=5\times 23.62$

$\text{Perimeter of community pool}=118.1$

Now let us find apothem of our pentagon by using Pythagoras theorem.

$a^2=20.10^2-11.81^2$

$a^2=404.01-139.4761$

$a^2=264.5339$

$a=\sqrt{264.5339}$

$a=16.2645$

Upon substituting our given values in above formula we will get,

$\text{Area of community pool}=\frac{1}{2}\times 16.2645\times 118.1$

$\text{Area of community pool}=8.13224907\times 118.1$

$\text{Area of community pool}=960.418615627971\approx 960.42$

Therefore, the area of the pool that needs to be covered is 960.42 square feet.

For the following right triangle, find the side length x

Liula [17]

Answer:

26

Step-by-step explanation:

To find the side length of a right triangle with the other two sides already, known, use the <em>Pythagorean Theorem, </em>

a²<em> </em>+ b² = c²

or

24² + 10² = x²

24 times 24 is 576,

10 times 10 is 100,

Add them together to get 676,

And then find the square root.

√676 = 26 :)

Rewrite the expression by factoring out (v-4).<br> 7v2(v - 4) – 3(v-4)

Shtirlitz [24]

Answer:

(7v²-3)(v-4)

Step-by-step explanation:

Rewrite the expression by factoring out (v-4).

7v²(v - 4) – 3(v-4)

Since (v-4) is common to both terms, we only pick one of it to have a factored form:

(7v²-3)(v-4)

The new expression will be (7v²-3)(v-4)
