Answers
The best statement and reason that completes the proof is option D that is,
statement- 2. ∠1 is supplementary to ∠2
reason- 2. linear pair theorem
To prove ∠1 ≅ ∠ 3, we can use the congruent supplements theorem. According to the congruent supplements theorem, If two angles are supplements of the same angle then two angles are congruent.
Line a and line b intersect (given)
∠3 is supplementary to ∠2 because of linear pair theorem (given)
So, if we take ∠2 as the common angle
And ∠1 is supplementary to ∠2 by linear pair theorem ( option D)
Then, ∠1 is supplementary to ∠2 which is supplementary to ∠3
Therefore, ∠1 ≅ ∠3 (according to the congruent supplements theorem)
Hence proved.
Therefore, the best statement and reason that completes the proof is
statement- 2. ∠1 is supplementary to ∠2

Option D, which is the following, is the finest statement and justification for concluding the proof.
statement 2. 1 is an addition to 2
2. The linear pair theorem
We can apply the congruent supplements theorem to demonstrate 1 and 3. The congruent supplements theorem states that two angles are congruent if they are supplements of the same angle.
Lines a and b come together (given)
Because of the linear pair theorem, 3 is an addition to 2 (given)
Thus, if we consider 2 to be the common angle
And the linear pair theorem enables 1 to be an addition to 2 ( option D)
Then, 1 is an addition to 2 which is an addition to 3
Consequently, 1 + 3 (according to the congruent supplements theorem)
So it was proved.
As a result, the strongest argument and supporting evidence are

Answer:
1.If you are to check the figure you will find that it is a rectangles. You should know the properties of a rectangle.
we are goin to use the property: Each vertex of a rectangle has angle equal to 90 degreesmeaning since m∠SUT and m∠ RUS form the vertex when added they give 90°3x+6+(5x-4)=90°
3x+5x+6°-4°=90°
8x+2°=90°

8x=8°

2.m ∠SUT is donated by 3x+6
and now we know the value of x=11°
m∠SUT=3(11°)+6
m∠SUT=33°+6°
m∠SUT=39°

A citrus farmer wants to know which of three fertilizers (A, B, and C) is most effective for increasing the number of oranges on his trees. He is willing to use 30 mature trees of various sizes from his orchard in an experiment with a randomized block design.
Which of the following is a correct step regarding the randomized block design of this experiment?
Step 1: It is reasonable to think that there is an association between the size of the tree and number of oranges produced. So to control this influence, the farmer should form blocks based on the size of the trees (small, medium, large).
Step 2: The farmer should randomly assign one-third of the small trees to fertilizer A, one-third to fertilizer B, and one-third to fertilizer C.
Step 3: The farmer should do the same allocation for the medium and large sized trees.
Step 4: In the end, the farmer should measure each tree’s orange production.

A department store advertises a sale where the customer chooses the discount. A customer may choose a flat discount of $20 off any purchase or 20% off the total purchase price. The final purchase price of an item was $175.
a. What are the possible prices of the item before each discount?
b. Which discount represents a bigger savings in cost for the customer?
Answers
The answers will be :
A. The possible prices at flat discount of $ 20 will be $195 and at flat discount of 20% will be $218.75
B. The discount of flat 20 % gives a bigger savings in cost for the customer.
What do you mean by discount ?
The discount is the difference between the purchase price and the item's par value or simply deduction from the cost price of a good.
It is given that the final purchase price of the item is $175.
A.
Let's try to find out the possible price of item before each discount.
So , price before discount can be calculated by using formula which is :
Price before discount = Discount + Final purchase price
As in first case the flat discount is of $20 , so :
Price before discount = $20 + $ 175
Price before discount = $195
Now as per the question , there is a flat discount of 20% off the total purchase price .
So , let's assume if price before discount is P then :
[ P - ( 20P / 100) ] = 175
P - 0.2 P = 175
0.8 P = 175
or
P = $ 218.75
B.
From the above calculations which we have done , we can conclude that the discount of 20 % represents a bigger savings in cost for the customer because customer is saving an amount of $218.75 which is greater than $195.
Therefore , the answers will be :
A. The possible prices at flat discount of $ 20 will be $195 and at flat discount of 20% will be $218.75
B. The discount of flat 20 % gives a bigger savings in cost for the customer.

What is the Max height formula?max = h plus V02 / (4 * g) When launching from the ground, the range is maximized (h = 0). If = 0°, therefore vertical velocity becomes equal to zero (Vy = 0), indicating horizontal projectile motion.

a. Does the situation represent a function? If so, identify the independent and dependent variables.The given parameters are
Initial Fee = $2.80
Rate = $3.50 per mile
Let the number of miles be x and the total fee be y
So, we have
Total fee = Initial Fee + Rate * Number of miles
This gives

According to a recent survey, 62 % of the population owns a cat. 37 Percent of cat owners are married, while 44 % of non-cat owners are married. If you randomly select a person, what is the probability that she/he is married?
Answers
Answer:
There are two possibilities that you need to take into account:
1) having a cat and being married
2) not having a cat and being married
P(having a cat) = 0.19
P(no cat) = 1 - P(having a cat) = 1 - (0.19) = 0.81
Since 9% of cat owners are married: (0.19)(0.09) = 0.0171
Since 11% of non-cat owners are married: (0.81)(0.11) = 0.0891
Probability of randomly selected person being married = 0.0171 + 0.0891 = 0.1062

By applying the supplementary angle theorem, the magnitude of angle B (m<B) is equal to 38°.
What is a supplementary angle?A supplementary angle can be defined as two (2) angles or arc whose sum is equal to 180 degrees.
Mathematically, a supplementary angle can be calculated by using this formula:
Q + R = 180
Where:
Q and R are measure of the angles subtended.
m<ADC = 180° - 110°
m<ADC = 70°
Substituting the given parameters into the formula, we have;
m<ADC + m<DAC + m<ACB = 180
70 + 46 + m<ACB = 180
116 + m<ACB = 180
m<ACB = 180 - 116
m<ACB = 64°
Now, we can determine the magnitude of angle B (m<B) based on the given diagram:
m<B = 180 - (m<CAB + m<ACB)
m<B = 180 - (78 + 64)
m<B = 180 - 142
