Help please I am very confused
Helga [31]

The sides of the triangle occur in a ratio of 4 : 7 : 2, so if <em>x</em> is some positive number, then we can write each side's length in terms of <em>x</em> as 4<em>x</em>, 7<em>x</em>, and 2<em>x</em>.

The perimeter is 299 yd, so

4<em>x</em> + 7<em>x</em> + 2<em>x</em> = 299 yd

13<em>x</em> = 299 yd

<em>x</em> = (299 yd) / 13

<em>x</em> = 23 yd

Then the sides of the triangle have lengths of

4<em>x</em> = 4 • 23 yd = 104 yd

7<em>x</em> = 7 • 23 yd = 161 yd

2<em>x</em> = 2 • 23 yd = 46 yd

"Median" here refers to the side length between the shortest and longest sides, so the answer would be 104 yd.

The regular octagon has a perimeter of 122.4 cm. Which statements about the octagon are true? Check all that apply.
Papessa [141]

Answer:

The length of segment XY can be found by solving for a in

20^2-7.65^2=a^2

The measure of the central angle \angle ZXW is 45\degree.

Step-by-step explanation:

If the regular octagon has a perimeter of 122.4cm, then each side is \frac{122.4}{8}=15.3cm

The measure of each central angle is \frac{360\degree}{8}=45\degree

The angle between the apothem and the radius is \frac{45}{2}=22.5\degree

The segment XY=a is the height of the right isosceles triangle.

We can use the Pythagoras Theorem with right triangle XYZ to get:

a^2+7.65^2=20^2

a^2=20^2-7.65^2

Therefore, the correct options are:

The length of segment XY can be found by solving for a in

20^2-7.65^2=a^2

The measure of the central angle \angle ZXW is 45\degree.

which of the following statements best describes midpoint of a line segment? 1. point at end of line segments 2. a point halfway
BARSIC [14]
<h2>Hello!</h2>

The answer is:

2. A point halfway between the endpoints of a line segment.

<h2>Why?</h2>

The midpoint of a line segment, is a point that divides the line segment into two equal length sides, no matter the length of the segment, the midpoint will always cut the segment into two equal length sides

The midpoint is an ordinary point located in the middle of the line segment. The x-coordinate of the midpoint is halfway between the x-coordinates of the beginning and the end of the segment. The y-coordinate of the midpoint is halfway between the y-coordinates of the beginning and the end of the segment.

Hence, the correct option is:

2. A point halfway between the endpoints of a line segment.

Have a nice day!
