A. disagree. There is not enough information to prove the triangles are congruent by SAS. There is no way to prove angles are congruent in this case. Since it is also not given, it should not be SAS.

B. SSS. Since all three sides are congruent, it can be proven congruent by SSS. Side AB and BC are congruent because it is bisected, and AB is congruent to AB because of Reflexive property. It is also given AD is congruent to DC, therefore it is congruent by SSS.

Hope this can help you! Please give me the brainliest answer if you like it! If you have more questions, please leave a comment or add me as a friend!

What is the value of x? <br> enter your answer in the box

Solnce55 [7]

Answer:

x = 20

Step-by-step explanation:

The two indicated angles are vertical angles and vertical angles are equal

3x+50 = 6x-10

Subtract 3x from each side

3x-3x+50 = 6x-10-3x

50 = 3x-10

Add 10 to each side

50+10 = 3x-10+10

60 = 3x

Divide each side by 3

60/3 = 3x/3

20 =x

26,) If y varies inversely as x, and y = 5 as x = 6, find y for the x-value of 10.

melisa1 [442]

Answer:

Step-by-step explanation:

the initial statement is

y ∝ 1 /x

to convert to an equation multiply by k the constant

of variation

y = k × 1 /x = k /x

to find k use the given condition

y = 5 when x = 6

y = k/ x ⇒ k = y x = 5 × 6 = 30

y = 30 /x

when

x = 10

then

y = 30 /10 = 3

The coordinates of the endpoint of QS are Q(-9,8) and S(9,-4). Point R is on cue as such that QR:RS Is in the ratio 1:2. What ar

marishachu [46]

R(–3, 4)

Step-by-step explanation:

Let Q(-9,8) and S(9,-4) be the given points and let R(x, y) divides QS in the ratio 1:2.

By section formula,

$R(x, y)=R\left(\frac{m x_{2}+n x_{1}}{m+n}, \frac{m y_{2}+n y_{1}}{m+n}\right)$

Here, $x_{1}=-9, y_{1}=8, \text { and } x_{2}=9, y_{2}=-4 \text { and } m=1, n=2$

Substituting this in the section formula

$R(x, y)=R\left(\frac{1(9)+2(-9)}{1+2}, \frac{1(-4)+2(8)}{1+2}\right)$

To simplifying the expression, we get

$\Rightarrow R(x, y)=R\left(\frac{9-18}{3}, \frac{-4+16}{3}\right)$

$\Rightarrow R(x, y)=R\left(\frac{-9}{3}, \frac{12}{3}\right)$

⇒ R(x,y) = R(–3,4)

Hence, the coordinates of point R is (–3, 4).

Jordan needs one can of juice to make 24 servings of a punch. How many servings of punch can she make with 1/2 a can of juice?

kati45 [8]

Compare the two sets of numbers with a ratio. 1 can for 24 servings is to 1/2 can for x servings.

x= # servings from 1/2 can

1/24= (1/2)/x
cross multiply

1 * x= 24 * 1/2

x= 24/2

x= 12 servings

ANSWER: She can make 12 servings from 1/2 can of juice.

Hope this helps! :)
