If two angles of one triangle are congruent to two angles in another triangle, then what must be true of the third angles of the triangles?

Answers

Answer 1

Final answer:

If two angles of one triangle are congruent to two angles in another triangle, the third angles must also be congruent since the sum of angles in any triangle must equal 180 degrees. This principle is supported by geometric theorems about the properties of triangles and the requirements for their congruence and similarity.

Explanation:

If two angles of one triangle are congruent to two angles in another triangle, then the third angles in both triangles must also be congruent. This is because the sum of the angles in any triangle must equal 180 degrees or two right angles. Since two angles are congruent in both triangles, whatever is left from the 180 degrees after subtracting these two angles must be what is left for the third angle, making them congruent by necessity.

There are several related theorems in geometry that confirm this. Theorem 11, also known as the Side-Angle-Side (SAS) Postulate, states that if one side and the two adjacent angles of two triangles are congruent, then the triangles are congruent. While this theorem refers mainly to the congruency of triangles, it supports our understanding that if two angles are congruent, the third must be as well to satisfy the congruence of all three angles.

Furthermore, in the context of similar triangles, when two triangles have congruent angles, they are similar, meaning all their angles are congruent, and their sides are in proportion. However, if we only consider the angles, as in the original question, knowing that two angles are congruent across two triangles is enough to deduct that the third angles will be congruent, regardless of side lengths or overall similarity.

Jovan bought a bond with a face value of 15,000 and a coupon rate of 8.5%. The bond will mature in 15 years. How much interest will he receive semiannually

Answers

Answer
19,125

Explanation
The value of bond has an interest of 8.5% annually. Monthly it will be 8.5/2%=4.25%
The initial value of bond is 15,000.
The formula for calculating the interest is;
Interest=PRT
Where p is the money deposited, R is the interest rate and T is the period.
Since the interest semiannually for 15 years, the interest period is (15×2) = 30.

Interest=15,000×0.045×30

Answers

To find the mean of the data, you will combine all values together and then spread them all out evenly to create one value that represents the data.


In math this involves adding the data together and then dividing the sum by how many pieces of data there are.


682 + 601 + 744 + 674 + 701 + 790 + 676 + 638 + 773 = 6279


6279/9 = 697.66...


The rounded credit score is 698 (Choice A).

Using the mean concept, it is found that the mean credit score in this group is given by:

a. 698

What is the mean?

Six times a number decreased by 10 is eight

Answers

If you're looking for an expression then it will be:

6n - 10 = 8
              6x                   -                    10  =  8
 Six times a number decreased by 10 is 8

Your equation is 
6x - 10 = 8

Now solve for x 
6x - 10 = 8

Add 10 to each side
6x - 10 + 10 = 8 + 10
6x = 18

Divide each side by 6
6x ÷ 6 = 18 ÷ 6
x = 3

If the ratio is 1:1 then the point must be a mid-point. Then the coordinate of the mid-point P is (–2, 8).

What is coordinate geometry?

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of line, etc.

If point P lies on segment AB with endpoints at A(-5,11) and B(1,5) such that AP:PB = 1:1.

We know that if the ratio is 1:1 then the point must be a mid-point.

Let the coordinate of point P be (x, y)

Then we have

[tex]\rm (x,y) = ( \dfrac{x_1+x_2}{2}, \dfrac{y_1+y_2}{2})\\\\(x,y) = (\dfrac{-5+1}{2}, \dfrac{11+5}{2})\\\\(x,y) = (\dfrac{-4}{2} , \dfrac{16}{2})\\\\(x,y) =(-2, 8)[/tex]

2x^2 if 0 4 if c is greater than or equal to 2
determine the following values of the function
f(-3)= __
f(2)= ___

Answers

We have a function [tex]f(x)[/tex] defined by two rules: if [tex]x \leq 0[/tex], [tex]f(x)=3x+1[/tex], and if [tex]x \geq 2[/tex], [tex]f(x)=2 x^{2} [/tex]. Notice that when you are evaluating a function at a number, you are basically saying that [tex]x[/tex] is equal to that number. So, when you say [tex]f(-3)[/tex], you are saying that  [tex]x-3[/tex]. Since [tex]-3 \leq 0[/tex], we are going to use our first rule to evaluate our function at -3:
[tex]f(x)=3x+1[/tex]
[tex]f(-3)=3(-3)+1[/tex]
[tex]f(-3)=-9+1[/tex]
[tex]f(-3)=-8[/tex]

Similarly, when you are evaluating the function at 2, you are saying that [tex]x=2[/tex]. Since [tex]2 \geq 2[/tex], we are going to use our second rule to evaluate our function:
[tex]f(x)=2 x^{2} [/tex]
[tex]f(2)=2(2^{2} )[/tex]
[tex]f(2)=2(4)[/tex]
[tex]f(2)=8[/tex]

We can conclude that [tex]f(-3)=-8[/tex] and [tex]f(2)=8[/tex].
Final answer:

To determine the values of the function f(x) at specific points, we need to look at the different cases given in the definition of f(x).

Explanation:

To determine the values of the function f(x) at specific points, we need to look at the different cases given in the definition of f(x).

If x is less than or equal to 0, then f(x) = 3x + 1. So, f(-3) = 3(-3) + 1 = -8.If x is greater than 0 and less than 2, then f(x) = 2x^2. So, f(2) = 2(2^2) = 8.If x is greater than or equal to 2, then f(x) = 4. So, f(2) = 4.

Therefore, f(-3) = -8 and f(2) = 4.

Answer: The difference is 6,050 feet.

To find the difference between the two values, you just have to subtract them.

Our problem is:  5895 - (-155) 

To do this, we change it to 5895 + 155 = 6050
We change it because we are subtract a negative number and subtracting a negative number is the same thing as adding it.

Answer:

Step-by-step explanation:

The difference between the altitudes will be the distance from the highest point of kilimanjaroto the lowest point on lake assai.

This distance will be the distance from the highest point of kilimanjaro to the sea level (5895m) plus the distance from the sea level to the lowest point on lake assai (155m, this distances wont be negative because it is taken as a distance from a point of reference not as a value below 0).

At a store, customers are randomly selected to participate in a survey. On Friday, there were 500 customers at the store. Out of all those people, 90 were selected to participate in the survey. On Saturday, the store manager expects 700 customers in the store. If the probability of being selected to participate in the survey on Saturday is the same as it was on Friday, how many customers will be selected to participate in the survey on on Saturday?

Answers

Divide the number of people selected by the total number of people.

90/500 = .18

This means that 18% of the customers were selected for the survey.

If the probability is the same on Saturday, then we can multiply the expected customers by our .18

700 x .18 = 126

126 should be selected for the survey on Saturday.

You have three cases:

1) the radicand is positive: you then have two dinstinct soutions, one with the root added to (-b) and then divided by 2a, and the other one with the root subtracted to (-b) and then divided by 2a.

2) the radicand is negative: you then have no solutions, because the root can't be performed. This case means that the given polynomial is never equal to zero.

3) the radicand is equal to zero: you then have the same value for both the solutions, which is -b/(2a).

Therefore your answer should be: C) when the radicand is equals to zero.

.. y = (5/2)x +8 . . . . . . . corresponds to selection (B)
so, a line that is parallel to 5x-2y = -12, will have the same exact slope as that equation's, so what is it anyway?

[tex]\bf 5x-2y=-12\implies 5x+12=2y\implies \cfrac{5x+12}{2}=y \\\\\\ \cfrac{5x}{2}+\cfrac{12}{2}=y\implies \stackrel{slope}{\cfrac{5}{2}}x+6=y[/tex]

Answers

Since the given angles are a linear pair, that means that they add up to 180 degrees (straight line). So we know that:
m∠ RQS + m∠ TQS = 180

Now let's answer the questions.
1. Solve for x
m∠ RQS + m∠ TQS = 180
2x + 4 + 6x + 20 = 180
2x + 6x + 4 + 20 = 180
(2 + 6)x + 24 = 180
8x + 24 = 180
8x = 156
x = 19.5

2. Find m∠ RQS and m∠ TQS
m∠ RQS = 2x + 4
m∠ RQS = 2*19.5 + 4
m∠ RQS = 39 + 4
m∠ RQS = 43


m∠ TQS = 6x + 20
m∠ TQS = 6*19.5 + 20
m∠ TQS = 117 + 20
m∠ TQS = 137

3. Show how you can check your answer.Verify that they do add up to 180.
So 43 + 137 = 180
This demonstrates that they do make up a linear pair.

Answers

You almost got it. Be careful with how the question is worded. A "common difference" between these sequential numbers already indicates subtraction. So you have to answer with what number is being subtracted from each number in order to equal the next. 9 - 10 is -1. Next, -1 - 10 is -11. Thus, the common difference between successive terms here is 10. Next, the difference between -11 and -21 is 10. You could continue the sequence: -21 - 10 = -31 and so on.

Which of the following polynomials corresponds to the product of the multivariate polynomials 4x - 3y + 5 and x + 2y - -3?

Answers

Final answer:

The product of the multivariate polynomials 4x - 3y + 5 and x + 2y - -3 is 4x^2 + 5x + 5xy - 16y^2 + 19y - 27.

Explanation:

The product of two multivariate polynomials can be found by multiplying each term in the first polynomial by each term in the second polynomial and then combining like terms. In this case, we have:

(4x - 3y + 5)(x + 2y - -3) = 4x(x + 2y - -3) - 3y(x + 2y - -3) + 5(x + 2y - -3)

Using the distributive property, we can simplify this to:

4x^2 + 8xy - 12x - 3xy - 6y^2 + 9y + 5x + 10y - -15

Combining like terms:

4x^2 + 5x + 5xy - 16y^2 + 19y - 27
