Quadrilateral ABCD is inscribed in circle O.
What is m∠C ?
Enter your answer in the box.
Answers
When you have an polygon inscribed in a circle, the opposite angles are supplementary.
Therefore, we can write and solve the following equation.
2x + 3 + 4x + 3 = 180
6x = 174
x = 29
If you substitution 29 into the expression for C, you will find that C = 59.
2(29) + 1 = 59
Good luck,

What is the rule for the reflection?
Will mark brainliest!
Answers
Answer:
Option C is correct.
[tex]r_{y=x} (x, y) \rightarrow (y, x)[/tex]
Step-by-step explanation:
From the given figure:
Coordinate of Triangle ABC are:
A(-2, 1), B(-3, 4) and C(-4, 1)
And
Coordinate of Triangle A'B'C' are:
A'(1, -2), B'(4, -3) and C'(1, -4)
The rule of reflection across the line:
[tex]r_{y=x} (x, y) \rightarrow (y, x)[/tex]
then;
Apply the given rule of reflection on coordinate of triangle ABC
[tex]A(-2, 1) \rightarrow (1, -2) =A'[/tex]
[tex]B(-3, 4) \rightarrow (4, -3) =B'[/tex]
[tex]C(-4, 1) \rightarrow (1, -4) =C'[/tex]
Therefore, the rule of reflection used here is [tex]r_{y=x} (x, y) \rightarrow (y, x)[/tex]

A = (0,s)
B = (r,0)
Add up the x coordinates to get 0+r = r. Then cut that in half to get r/2
Similarly, do the same for the y coordinates: s+0 = s ---> s/2
So the location of point D is (r/2, s/2)

What would a monthly payment be on a purchase of $12000 car at 4.9% for 5 years?
Answers
Answer: it's 225.41 but your answer helped!
Step-by-step explanation:
The monthly payment will be $249
Firstly, we will calculate the simple interest which will be:
= PRT/100
where,
P = principal = $12000
R = rate = 4.9%
T = time = 5 years
Simple Interest = PRT/100
= ($12000 × 4.9 × 5)/100
= $294000/100
= $2940
Then the total amount to be repaid will be: = Principal + Interest
= $12000 + $2940
= $14940
We'll convert 5 years to months and this will be: = (5 × 12) = 60 months.
The monthly payment will then be:
= $14940/60
= $249
In conclusion, the monthly payment will be $249

Answers
Not Factored: (5x^2 - 13x - 6)
Factored: (5x + 2 )(x - 3)
There is no real "work" to be shown for this, you can see that
1) Seperating 5x^2 into 5x and x will get you the equation in the form:
(5x ) (x ) = 5x^2 +
2) To complete this factor you need to guess which two numbers will add together to give you - 13x and multiply to form -6 (from the original unfactored equation). The numbers that will do this are 2 and 3
3) You can plug in negative or positives of those numbers to make sure they give you the exact results you need.
For example testing -2 and 3 you will get: (5x - 2) (x + 3 ) = 5(x^2) - 2x + 15x - 6 = 5x^2 +13x - 6. This is NOT the same as the unfactored equation. So you know -2 and 3 is the wrong choice. Choosing 2 and -3 will give you the answer instead.
As i said, there's no actual "work" to show this, you have to make guesses and try to factor it.

Factored: 4x^2 (x^2 - 7x + 12) =

To solve this, you factor out the 4x^2 from the entire equation. Then you can further factor the quadratic equation by seperating x^2 into (x )(x ) and guessing for which numbers will add to -7x and multiply to 12

4. 2p – 6 = 88
5. 2p = 94

Answers
m∠ABC=180-[(p+4)+84]--------> 180-[p+88]=92-p
m∠ABC=(92-p)° equation 1
and
m∠ABC+(3p-6)=180----------m∠ABC=180+6-3p
m∠ABC=186-3p equation 2
(1)=(2)
(92-p)=186-3p-----------> 186-92=-p+3p--------------> 2p=94
p=47°
therefore
m∠XBC=(3p-6)°---------->(3*47-6)=135°
the answer is
m∠XBC=135°
The measure of an exterior angle of triangle is equal to the sum of measures of two interior angles of triangle that are not supplementary with this exterior angles.
In the case of this question this fact sounds as
m∠XBC = m∠BAC + m∠BCA (option 1).
Now if
m∠XBC=(3p-6)°m∠BAC=(p+4)°m∠BCA=84°,then
3p-6=p+4+84 (option 2),
3p-6=p+88 (option 3),
3p-p-6=p-p+88,
2p-6=88 (option 4),
2p-6+6=88+6,
2p=94 (option 5),
p=47.
Then m∠XBC=(3p-6)°=(3·47-6)°=135°.
Answer: m∠XBC=135°.

1. Given a || b , c || d, and . Find the measure of angles 1 through 12 in the complex figure.
Answers
To solve all of the angles that are listed you are going to have to set up and solve several equation involving supplementary angles and angles around traversals around parallel lines.
For example, you could set up the equation:
3 + 4 + 69 = 180
Also, angle 9 is 116 because they are alternate interior angles.
Also, angle 11 is 116 because the are corresponding angles.
Also, angle k can be solved with the equation: k + 12 + 90 = 180.
Good luck
In summary:
- Angle 1 = Angle 2 = Angle 3 = Angle 4 = 69°
- Angle 5 = Angle 6 = Angle 7 = Angle 8 = 116°
- Angle 9 = Angle 10 = 69°
- Angle 11 = Angle 12 = 116°
Let's analyze the complex figure with parallel lines and transversals. We have two parallel lines, a and b, intersected by two transversals. I'll break down the problem step by step:
1. Angle 1: This angle is formed by the intersection of a and the transversal. It is an **alternate interior angle** with the angle measuring 69°. Therefore, **Angle 1 = 69°**.
2. **Angle 2**: It is also an alternate interior angle with the same measure as **Angle 1**. Hence, **Angle 2 = 69°**.
3. **Angle 3**: This angle is formed by the intersection of **b** and the transversal. It is a **corresponding angle** to **Angle 1**. Therefore, **Angle 3 = 69°**.
4. **Angle 4**: It is a corresponding angle to **Angle 2**. Thus, **Angle 4 = 69°**.
5. **Angle 5**: This angle is formed by the intersection of **c** and the transversal. It is an **alternate interior angle** with the angle measuring **116°**¹. Therefore, **Angle 5 = 116°**.
6. **Angle 6**: It is also an alternate interior angle with the same measure as **Angle 5**. Hence, **Angle 6 = 116°**.
7. **Angle 7**: This angle is formed by the intersection of **d** and the transversal. It is a **corresponding angle** to **Angle 5**. Therefore, **Angle 7 = 116°**.
8. Angle 8: It is a corresponding angle to Angle 6. Thus, Angle 8 = 116°.
9. Angle 9: It is a vertical angle to Angle 1. Therefore Angle 9 = 69°.
10. Angle 10: It is a vertical angle to Angle 2. Thus Angle 10 = 69°.
11. Angle 11: It is a vertical angle to Angle 5. Therefore, Angle 11 = 116°.
12. Angle 12: It is a vertical angle to Angle 6. Thus, Angle 12 = 116°.

Find the amount paid for the loan.
$2400 at 10.5% for 5 years
Answers
Final answer:
$3,919.24
Explanation:
To calculate the total amount paid for a loan of $2,400 at an interest rate of 10.5% over 5 years, we will assume the interest compounds annually for simplicity. The formula to find the future value of a loan including interest is P(1 + r)^n, where P is the principal amount ($2,400), r is the annual interest rate (10.5% or 0.105), and n is the number of years (5).
Plugging the numbers into the formula gives us $2,400(1 + 0.105)^5. Calculating this gives us approximately $3,919.24. Therefore, the total amount paid for the loan over 5 years would be $3,919.24.
To find the amount paid on a $2400 loan at 10.5% interest for 5 years, calculate the simple interest and add it to the principal. The total interest is $1260, bringing the total repayment amount to $3660 over 5 years.
To find the amount paid for the loan of $2400 at 10.5% interest for 5 years, one would typically use the formula for the compound interest or an installment payment plan depending on whether the loan is paid off in a lump sum at the end of the term or through regular payments over the term. However, you have not specified the method of repayment (lump sum or installments), so let's consider a simple interest scenario which is often used for short-term loans.
The simple interest can be calculated as:
I = PRT
Where:
I = Interest
P = Principal amount ($2400)
R = Annual interest rate (10.5% or 0.105 in decimal)
T = Time in years (5)
Using the formula:
I = $2400 × 0.105 × 5 = $1260
Therefore, the total interest paid over 5 years is $1260. To find the total amount paid for the loan, add the interest to the principal:
Total Amount Paid = Principal + Interest
Total Amount Paid = $2400 + $1260 = $3660
The borrower would have to pay a total of $3660 after 5 years.

Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
To graph y = f (x) -k, move the graph of k units down.
