D. the segment DE is bisects segment AC
----------------
The true statements for the triangle ABC where DE is perpendicular to AC is given by option D. The segment DE bisects the segment AC.
In triangle ABC, B-D-C, and A-E-C, with E being perpendicular to AC and AE = EC.
A. The segment BD bisects the segment EC.
This statement is false. Since E is the midpoint of AC (AE = EC), and E is perpendicular to AC, B-D-C no relation.
B. The segment ED is congruent to the segment DC.
This statement is not necessarily true. We only know that AE = EC, which implies that DE = EC since E is the midpoint of AC. However, we don't have enough information to conclude that ED is congruent to DC.
C. The segment BD is perpendicular to the segment EC.
This statement is not necessarily true. While we know that E is perpendicular to AC, it does not imply that BD is perpendicular to EC.
The perpendicularity of BD and EC depends on the specific configuration of the triangle, and the given information is not sufficient to determine this relationship.
D. The segment DE bisects the segment AC.
This statement is true. Since E is the midpoint of AC (AE = EC), DE passes through E and will indeed bisect AC.
Therefore, the true statements for the given triangle is
option D. The segment DE bisects the segment AC.

∠E and ∠F are vertical angles with m∠E=8x+8 and m∠F=2x+38 . What is the value of x? Enter your answer in the box.
Answers
Answer:
x = 5
Step-by-step explanation:
We need to remember that vertical angles are opposite to each other when two lines cross. The vertical angles that result from two lines crossing have the same measure.
In this problem we have angle E which measures 8x + 8 and angle F which measure 2x + 38.
Since they are vertical angles, we know that they have the same measure and therefore we can equal them both and solve for x:
[tex]8x+8=2x+38\\8x-2x=38-8\\6x=30\\x=5[/tex]
Therefore, x = 5 (and ∠E = ∠F = 48)
The measure of each interior angle of a regular polygon is 140 degrees, how many sides does the polygon have
Answers
[(n-2)180]÷n = 140
(n-2)180 = 140n
180n -360 = 140n
180n -140n = 360
40n = 360
n=360÷4 = 90 sides
The regular polygon with an interior angle of 140 degrees has 9 sides. This conclusion can be reached by using the formula for the interior angle of a polygon, which is (n-2)*180/n, where 'n' represents the number of sides.
Explanation:
The number of sides in a regular polygon can be determined using the formula for the interior angle of a polygon, which is (n-2)*180/n, where 'n' represents the number of sides. This formula comes from the fact that a polygon can be divided into (n-2) triangles, each of which has angles summing up to 180 degrees.
In this particular case, an interior angle of 140 degrees is given. So we will set up an equation: 140 = (n-2)*180/n. Solving for 'n', we get a value of 9.
Therefore, the regular polygon with an interior angle of 140 degrees has 9 sides.

What is the equation of a line passing through the points 6,3 and -4,3 so y=?
Answers
Answer:
y=3
Step-by-step explanation:
The required line will be y = 3 which is passing through points (6,3) and (-4,3)
What is the slope of the line?The slope of the line is defined as the gradient of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
To determine the line of passing through points (6,3) and (-4,3)
We have been given two points :(6,3) and (-4,3)
Let the required line will be:
(y - y₁) = [(y₂ - y₁)/(x₂ -x₁ )](x -x₁ )
Here
x₁ = 6, y₁ = 3
x₂ = -4, y₂ = 3
(y - y₁) = [(y₂ - y₁)/(x₂ -x₁ )](x -x₁ )
Substitute values in the above formula
(y - 3) = [(3 - 3)/(-4 -6 )](x -6 )
(y - 3) = [(0)/(-10 )](x -6 )
(y - 3) = 0
y = 3
Therefore, the required line will be y = 3

You are offered an item for $17.85. If the seller states he normally sells the same item for $19.95, what percentage discount is he offering you?
Answers
Answer:
Find out the what percentage discount is seller offering you .
To prove
Formula
[tex]Discouunt\ percentage = \frac{Discount\times 100}{Marked\ price}[/tex]
Discount = Marked price - Selling price
As given
You are offered an item for $17.85. If the seller states he normally sells the same item for $19.95 .
Here
Marked price = $19.95
Selling price = $17.85
Discount = 19.95 - 17.85
= $2.1
Put in the formula
[tex]Discouunt\ percentage = \frac{2.1\times 100}{19.95}[/tex]
[tex]Discouunt\ percentage = \frac{210}{19.95}[/tex]
Discount percentage = 10.5% (Approx)
Therefore the discount is seller offering you is 10.5 % .

The scale on a map of Texas shows that 1 inch represents 20 miles. The actual distance from Austin to Dallas is 195 miles. On the map, how many inches apart are the two cities?
Answers
so 195 miles is 195/20 = 9.75 inches <==
To calculate the map distance between Austin and Dallas with a scale of 1 inch representing 20 miles, and an actual distance of 195 miles, set up a proportion and solve to find that Austin and Dallas would be 9.75 inches apart on the map.
Explanation:To find out how many inches Austin is from Dallas on the map, we need to set up a proportion. The scale given on the map is 1 inch represents 20 miles. We know the actual distance between Austin and Dallas is 195 miles. To calculate the distance on the map, we use the proportion 1 inch / 20 miles = x inches / 195 miles.
Cross-multiply to solve for x:
(1 inch) * (195 miles) = (20 miles) * (x inches)
195 inch-miles = 20x inch-miles
Now, divide both sides by 20 miles to solve for x:
x = 195 inch-miles / 20 miles
x = 9.75 inches
So, on the map, Austin and Dallas would be 9.75 inches apart.
How is the distance formula like the pythagorean theorem explain?
Answers
The distance formula is
simply a variation of the theorem. The method is the same with the Pythagorean
however we are now dealing with 2 sets of points instead of 2 lengths.
In the distance formula, the lengths are derived from the
(x1,y1)->(x2,y2) coordinate points and the formula simplified. We still
square the difference of x’s and difference of y’s to get our two squares then
square root the sum to give our length. While the Pythagorean theorem is
directly the sum of the square of the other two sides.
Nevertheless, both formulas work on the same principle.
Answer:
Both formulas can be used to find the distance between two points on the coordinate plane. The vertical leg of the right triangle represents the difference in the y values of the two points. The horizontal leg of the right triangle represents the difference in the x values of the two points. The hypotenuse of the right triangle represents the distance between the two points.
