You'll need 2 more lines to complete this two column proof.
---------------------
Line 4
For the "statement" portion, you'll say something like
The reason for this statement is "transitive property"
We're basically combining lines 1 and 3 to form this new line.
The transitive property is the idea that if A = B and B = C, then A = C. We connect the statements like a chain.
---------------------
Line 5
The statement is what you want to prove since this is the last line.
So the statement is
The reason is "converse of corresponding angles theorem"
As you can probably guess, this theorem says "If two corresponding angles are congruent, then the lines are parallel".
To prove that lines P and Q are parallel based on congruent angles, utilize the geometric understanding that if a transversal intersects two parallel lines, the corresponding angles are congruent. Given that angle 1 is congruent to angle 2, we can infer that the lines forming these angles (P and Q) are parallel.
To prove that the lines P and Q are parallel using the fact that angle 1 is congruent to angle 2, you will utilize the concept of congruent angles. When two parallel lines are intersected by a transversal, the corresponding angles are congruent. Therefore, if we know that angle 1 is congruent to angle 2, we can say the lines forming these angles are parallel.
Here are the steps:
This process uses reasoning of the geometry and reviews the core concept of parallel lines and transversals in proving that P is parallel to Q.

The length of the line on the blueprint of the wall will be 18 inches.
Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
There is no effect of dilation on the angle.
An architect uses a scale of 3/4 inches to represent 1 foot on a blueprint for a building.
Then the scale factor of the blueprint will be
Scale factor = 3/4 inches per foot
If the east wall of the building is 24 feet long.
Then the length of the line on the blueprint of the wall will be
Length = 24 feet x scale factor
Length = 24 x (3/4)
Length = 6 x 3
Length = 18 inches
Thus, the length of the line on the blueprint of the wall will be 18 inches.
More about the dilation link is given below.

Answer:
16 in.
Step-by-step explanation:
We have the ratio
How about let's make this easier. Easier is better, right? Let's get rid of the fraction 2/3. We will do that by multiplying 2/3 by 3 and 1 by 3 to get the equivalent ratio of
Now we need to know how many inches there would be if the number of feet is 24:
Cross multiply to get
3x = 48 so
x = 16 in.
Answer:
infinite rational numbers
Step-by-step explanation:
There are infinite rational numbers between 0 and 4. Now,single decimal value change like 2.34 and 2.35 can change the total value of a rational number. And there are infinite combinations of this decimal value between just two numbers.

4. x=4
5. x=-8
6. x=8
Step-by-step explanation:
It may take one extra step to get to the solution, but this method always works.
1. find the variable term that is smallest or most negative. Subtract all the terms on that side of the equation from both sides of the equation.
2. collect terms
3. divide the equation by the coefficient of the variable
4. add the opposite of the constant
___
4. The most negative variable term is -9x, which is on the left side. Subtracting (24-9x) from both sides of the equation, we have ...
0 = -3x -24 +9x
0 = -24 +6x
0 = -4 +x . . . . . divide by 6
4 = x . . . . . . . . add the opposite of -4
__
5. The smallest variable term is 18x, on the right. (The variable term on the left is 20x.)
4(5x +2) +11 -18x -3 = 0 . . . subtract the right side
2x +16 = 0 . . . collect terms
x +8 = 0 . . . . . . divide by 2
x = -8 . . . . . . . . add -8
__
6. All variables are on the left side, so we can just collect terms and divide by the coefficient of the variable.
-5x = -40 . . . collect terms
x = 8 . . . . . divide by -5
If you were to literally follow the steps above, you would recognize that -5x is less than 0x (the x-term on the right side of the equation), so you would subtract the left side, giving ...
0 = 5x -40
0 = x -8 . . . . . divide by 5
8 = x . . . . . . . . add 8

Comment on this solution technique
You will often be told to solve these equations by separating the variable terms from the constant terms. This method actually puts the variable terms and constant terms together (and zero on the other side of the equal sign). The constant is separated from the variable as the last step of this solution process, rather than as one of the first steps. By doing this, we don't have to worry about which variable term or which constant term we're going to mess with.
The only reason for choosing the variable term with the smallest (least) coefficient in the first step is to ensure that the resulting variable coefficient is positive. This tends to reduce errors later on. You can also use that same strategy when solving the equation following the "separate constant terms and variable terms" approach.
for 16 square rooms in a
hotel. Each room will need
100 square feet of
carpet. What is the
length of 1 room?
Answer:
Length of a room is 10ft
Step-by-step explanation:
Given
Required
Determine the length of each room
Here, we'll assume that the carpet will cover each room completely.
If so:
Take square root of both sides
Take positive square root
Hence, the length of a room is 10ft
I. Triangle ABC could be a right triangle.
II. Angle C cannot be a right angle.
III. Angle C could be less than 45 degrees.
We have altitude h to side AB and AB=h, i.e. the altitude is congruent to the side it goes to.
That's all kinds of triangles. One way to see them is using two horizontal parallel lines h apart, the bottom one with a base AB=h somewhere on it. Then any C on the top line makes a triangle ABC with altitude h=AB.
Let's go through the choices.
I. ABC could be a right triangle. That's TRUE.
We could have the isoscleles right triangle, C directly above B, so AC is the leg and an altitude, AB=AC and B is the right angle.
II. Angle C cannot be a right angle. That's TRUE.
The biggest angle C can be is when it's over the midpoint of AB, so if AB=2, h=2, and
so
III. Angle C could be less than 45 degrees. That's TRUE.
As long as C stays on our top parallel, we can make it as acute as we like by going farther away from AB.
All true. Hmmm.
