In isosceles triangle QRS, RT is the angle bisector of ∠QRS. Mikah begins the proof by stating ∠1≅∠2. What is a valid reason for this statement? Please HELP ME!
A. Definition of Angle Bisector
B. Reflexive Property of Congruence
C. Symmetric Property of Congruence
D. Corresponding angles are congruent.
Answers
Answer:
its a
Step-by-step explanation:
Segment RT bisects ∠QRS in ΔQRS and therefore, the angles ∠1 and ∠2
formed are equal.
The valid reason for the statement ∠1 ≅ ∠2 is; A. Definition of Angle Bisector.
Reasons:
The information on the triangle ΔQRS are;
The angle bisector of ∠QRS = RT
Therefore;
∠QRT = ∠1, ∠SRT = ∠2 Given in the diagram
∠QRS = ∠QRT + ∠SRT by angle addition property
∠QRT ≅ ∠SRT by definition of angle bisector
∠1 ≅ ∠2 by definition of ∠QRT and ∠SRT
By substituting ∠QRT with ∠1 and ∠SRT with ∠2, we have;
∠1 ≅ ∠2 by definition of angle bisector
The valid reason for the statement is therefore; A. Definition of angle
bisector.

Jade has $22 to spend at the grocery store. He is going to buy bags of Takis that cost $4 each and one box of Oreos that costs $3.50. Write and solve an inequality that models this situation, and could be used to determine the maximum number of bags of takis, t, that Jade can buy.
Answers
Answer:
4 bags of takis
Step-by-step explanation:
take the $22 and subtract the $3.50 for the oreos, this leaves you with $18.50.
now, take the $18.50 and divide that by $4 (the amount takis cost) and you will find out how many bas he will he able to buy.
18.50/4 = 4.6 he will be able to buy only 4 bags and will have $2.50 left over

What is the equation of the line passing through points (1.1) and (3.-5)
Answers
Answer:
Step-by-step explanation:
Any line has an equation ax+by+c=0 with some constants a, b and c. Because your line passes through the points (-1,1) and (3,5), you have two equations, -a+b+c=0 and 3a+5b+c=0. If you find a solution to these equations, you will find an equation of your line.

Coordinates of W' → (3, 3)
Coordinates of U' → (5, 4)
Step-by-step explanation:
If the given figure is dilated about a point (4, 3) by a scale factor k = [tex]\frac{1}{2}[/tex]
Then the length of each side will get reduced to half of its original length.
(As in the figure attached)
Scale factor = [tex]\frac{\text{Side length of image}}{\text{Side length of preimage}}[/tex]
[tex]\frac{1}{2}=\frac{V'U'}{VU}[/tex]
V'U' = [tex]\frac{1}{2}(VU)[/tex]
Now from the graph,
Coordinates of W' → (3, 3)
Coordinates of U' → (5, 4)
What is the value of x in this figure?
Answers
Answer:
x = 65 degrees
Step-by-step explanation:
Sum of all three sides in a triangle is 180
48 + 67 + n = 180
180 - (48 + 67) = 65
The missing angle and angle X are vertical angles, so they are the same angle.
angle X = 65 degrees

what is a -210 Divided by 14
Answers
Answer:
-15
Step-by-step explanation:
Well you cleary just divide the numbers But if you dont belive it use a caculator for this
-210 divided by 14 equals -15.
To divide -210 by 14, we set up the division equation: -210 ÷ 14.
Since we have a negative dividend, we know the quotient will also be negative.
We divide the absolute values of the numbers: 210 divided by 14, which equals 15.
Since the dividend and divisor have different signs, the quotient is negative.
Therefore, -210 divided by 14 equals -15.
This means that -210 can be evenly divided into 14 groups, each having a value of -15.
The negative sign indicates that the result is in the opposite direction or orientation compared to the positive value.

Given hexagon LMNOPQ is congruent to hexagon L'M'N'O'P'Q'. What is the measure of OP?
6 in
7 in
45 in
51 in
Answers
Answer:
51in
Step-by-step explanation:
Just set the equations of line OP and line O'P' equal to one another, then solve for x.
ie: 3(2x+3)=(8x-5)
To solve for x, distribute first. Then, subtract 6x from each side. Then, add 5 to each side.
ie: 6x+9=8x-5
ie: 14=2x
Now divide by 2.
ie: 7=x
Now that you have your x value, plug it back into one of the equations and solve for the measure of line OP. To check you answer, plug 7 for x into the equation where they are set equal, then solve them both and if the end result is true (51=51) it is correct.

Step 1: Define Equation
3x - 6 = 9
Step 2: Solve for x
Add 6 to both sides: 3x = 15Divide 3 on both sides: x = 5Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(5) - 6 = 9Multiply: 15 - 6 = 9Subtract: 9 = 9Here we see that 9 does indeed equal 9.
∴ x = 5 is the solution to the equation.

illuminated.
PLEASE HELPPPPPPP!!!!!!!!!!!
Answers
Answer:
Day 13= 50%
Day 26=100%
Step-by-step explanation:
Answers vary. Sample response: A simple approach is to attempt a linear model starting at Day 1. If the illumination is increased by 4% every day, then after 11 more days (after Day 2) it reaches 50%. In 13 more days, illumination reaches 100%. This gives a prediction of Day 13 for 50% and Day 26 for 100%.
The days where it is illuminated is Day 13= 50% and Day 26=100%
Linear model:Here A simple approach should be considered for linear model that begins at Day 1. In the case when the illumination is increased by 4% every day, so after 11 more days (after Day 2) it reaches 50%. In 13 more days, illumination reaches 100%.
Therefore, we can conclude that The days where it is illuminated is Day 13= 50% and Day 26=100%

Cnidarians are another major group of invertebrates. Jellyfish, coral, hydra and anemone are examples of cnidarians. They have soft bodies and no heads. They have stinging tentacles that they use for defense and to capture prey. Cnidarians have radial symmetry. That means that their parts are arranged around a center. If you were to draw a line to cut them in half in any direction, the two sides will always match. Radial symmetry is often a characteristic of more simple animals than bilateral symmetry, where there is only one line you could draw to make two sides match. With bilateral symmetry, different body parts may have different functions. With radial symmetry, the entire body may perform all life functions.
