For which pair of triangles would you use AAS to prove the congruence of the 2 triangles

Mathematics
2 answers:
DerKrebs [107]3 years ago
8 0

Answer:

The correct option is B.

Step-by-step explanation:

According to AAS congruence rule, two triangles are congruent if two angles and a non included side are congruent to corresponding angles and side of another triangle.

We need two angles and a non included side, to use AAS postulate.

In option A, two sides and their inclined angle are congruent, therefore these triangles are congruent by SAS postulate and option A is incorrect.

In option B, two angles and a non included side are congruent, therefore these triangles are congruent by AAS postulate and option B is correct.

In option C, two angles and their included side are congruent, therefore these triangles are congruent by ASA postulate and option C is incorrect.

In option D, all sides are congruent, therefore these triangles are congruent by SSS postulate and option D is incorrect.

Which of the following are solutions to the equation below?
Zarrin [17]

Answer:

D, E

Step-by-step explanation:

(4x - 1) ^2 = 11      =>             (take square roots of both sides)

4x - 1 = +\- sqrt(11)  =>           (Add 1 to both sides)

4x - 1 + 1 = 1 +\-sqrt(11) =>

4x + 0 = 1 +\- sqrt(11) =>        (Divide both sides by 4)

x = ( 1 +\- sqrt(11) ) /4

Which are choices D and E

Please someone help with this
Kryger [21]

ok, i will help you.

For the first equation, we have points

(-1, -4)

and

(1, -1)

we also know the y-intercept is

(0, -2)

we can make systems of equations to solve for the equation of this exponiental function

y=ab^x

-1=ab

-2=a*1

a=-2

-1=-2(b)

b=1/2

The exponiental fufnction here is y=(-2)(1/2)^x

2nd equation

(0, 6)

(1, 12)

12=ab

6=a*b^0=6

a=6

12=6(b)

b=2

2nd equation is

y=6(2)^x

Your company has just taken out a 1-year installment loan for $72,500 at a nominal rate of 20.0% but with equal end-of-month pay
Mariulka [41]

Answer:

100% of the 2nd monthly payment go toward the repayment of principal.

Step-by-step explanation:

The loan taken is the Principal which is mentioned as $72,500 with interest at a nominal rate of 20%. Firstly, it is important to understand that nominal rate means <em>non-compounding </em>rate. Simply put will be a "<em>one-time charged" </em>rate on the loan. Since this is given as 20% of the Principal. It is calculated thus: \frac{20}{100} × \frac{72,500}{1}= $14,500. So the interest on the loan is $14,500. Added to the Principal the total amount to be paid back by the company becomes: $72,500 + $14,500 = $87,000. To pay back this amount at equal end-of-month installments in 1 year (12 months), we divide the total amount by 12. i.e \frac{87000}{12} = $7250. This means, the monthly payment will be $7,250. Since the monthly payment pays only 10% of the initial principal $72,500. By the second month only 20% of the Principal would have been paid. So all of the monthly payment will go towards repaying the principal

I need help it’s a quiz
solmaris [256]

Answer:

Question 6: 26 crowns plus 15 ribbons.

Question 7: 10 footballs plus 42 basketballs.

Step-by-step explanation:

Question 6 explanation: Since the expression is 22 crowns plus 13 ribbons plus 2 ribbons plus 4 crowns, you can think of the different items as variables in an equation. Picture crowns are the variable x, and ribbons as the variable y, this will help you solve the equation in an easier way that allows you to comprehend each step better. The equation will now be 22x+13y+2y+4x, in order to find how many x (crowns) and y (ribbons) you have, you need to combine like terms in the expression. In other words, add the terms with the variable x together, and add the terms with the variable y together. Simplified, the equation will be 26x+15y. Since the variables x and y were used to represent crowns and ribbons respectively, that means the correct answer is 26 crowns plus 15 ribbons.

Question 7 explanation: You can use the same method as you did in question 6, think of footballs and basketballs as the variables x and y respectively. The equation will be 16x+38y-6x+4y = 10x+42y. Since the variable x was used to represent footballs and the variable y was used to represent basketballs, that means the correct answer would be 10 footballs plus 42 basketballs.
