If triangle ABC is reflected across the line y = x, are the pre-image and image congruent? Why, or why not?
OYes, distance and angle measure are preserved
OYes, angle measure is preserved and distance is not
O No, distance is preserved but angle measure is not
O No, neither distance nor angle measure are preserved
The correct answer is: O Yes, distance and angle measure are preserved.
When a triangle ABC is reflected across the line y = x, the pre-image and image are congruent.
This is because the line y = x is the perpendicular bisector of the segment joining each corresponding point of the pre-image and image.
Reflection across the line y = x is a type of transformation known as an isometry, which preserves both distance and angle measure.
Here's why:
Distance preservation:
When a point is reflected across the line y = x, the distance between the original point and its reflection remains the same.
This holds true for all corresponding points of the triangle.
Therefore, the distance between any two corresponding points in the pre-image and image triangle will be equal, resulting in distance preservation.
Angle preservation: When a line segment is reflected across the line y = x, the angle between the line segment and the line y = x is preserved. This means that the corresponding angles in the pre-image and image triangle will be congruent.
Since both distance and angle measure are preserved during reflection across the line y = x, the pre-image and image triangles are congruent.
It's important to note that congruence under reflection across a line holds only when the line of reflection is the same for both the pre-image and image.
If the line of reflection were different, the triangles would not be congruent.

The volume of a cube is found by:
1. l x w x h
2. l x w
3. w x h
Answer:
1)
Step-by-step explanation:
l x w and w x h are all formula for a rectangle, not a cube.
For instance, let's take l x w. If we change the height it will definitely change the volume, but according to 2) it won't. So, 2 is wrong.
We can do the same process for 3) to show it's wrong.
So, the answer is not 2) or 3), so it must be \(\boxed{1)}\)

Answer:
96.25%
Step-by-step explanation:
The empirical rule regarding mean and standard deviation is that
Around 68% of scores are between 40 and 60.Around 95% of scores are between 30 and 70.Around 99.7% of scores are between 20 and 80.Therefore between mean and +2 standard deviation or between mean and -2 standard deviation you will find approximately 95/2 = 47.5% of the values
Between mean and ± 3 standard deviations you will find approximately 97.5/2 = 48.75% of the values
Therefore between 2 standard deviations above and 3 standard deviations below you will find approximately 47.5 + 48.75 = 96.25% of values

Define a mixed number?A mixed number is a kind of fraction that also has a proper fraction and a whole number. The number of whole units is represented by the whole number, and the fraction of a unit is represented by the proper fraction.
To solve the problem, we have to convert the mixed number \(9 \frac{1}{10}\) to a decimal number:
⇒ \(9 \frac{1}{10} = 9 +\frac{1}{10} = \frac{(9*10)+1}{10}\)
⇒ \(\frac{91}{10}\) = 9.1
This means that Emily finished making dinner 9.1 minutes sooner than the cake.
To find out how long it took Emily to make dinner, we can subtract 9.1 from the cake baking time:
⇒ 42.5 - 9.1 = 33.4 minutes
Therefore, it took Emily 33.4 minutes to make dinner.

What is the area of the square that measures 3.1 m on each side
The area of the square with a side length of 3.1 meters is 9.61 square meters.
To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.
Area of a square = side length × side length
Substituting the given side length into the formula:
Area = 3.1 m × 3.1 m
To perform the calculation:
Area = 9.61 m²
It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.
Remember, to find the area of any square, you simply need to multiply the length of one side by itself.

The values of the variables in number 3, in simplest radical form, are:

How to Find the Values of the Variables in the Simplest Radical Form?The simplest radical form, also known as simplified radical form or simplified surd, refers to expressing a square root (√) or other roots in the simplest possible way without any perfect square factors in the root. In other words, it involves reducing the radical expression to its simplest form.
Solving problem 3, we would apply the necessary Trigonometric ratios to find the variables:
sin 60 = opp/hyp
sin 60 = 9√3 / f
f = 9√3 / sin 60
f = 9√3 / √3/2 [sin 60 = √3/2]
f = 9√3 * 2/√3
f = 18/3
f = 6
tan 60 = opp/adj
tan 60 = 9√3 / o
o = 9√3 / tan 60

Answer:
o = 9
f = 18
Step-by-step explanation:
Triangle #3 is a right triangle with two of its interior angles measuring 60° and 90°. As the interior angles of a triangle sum to 180°, this means that the remaining interior angle must be 30°, since 30° + 60° + 90° = 180°. Therefore, this triangle is a special 30-60-90 triangle.
The side lengths in a 30-60-90 triangle have a special relationship, which can be represented by the ratio formula a : a√3 : 2a, where "a" represents a scaling factor that can be any positive real number.
Side a is opposite the 30° angle (shortest leg).Side a√3 is opposite the 60° angle (longest leg).Side 2a is the hypotenuse (longest side).In triangle #3, the longest leg is 9√3 units.
As "a√3" is the shortest leg, the scale factor "a" is 9.
The side labelled "o" is the shortest leg opposite the 30° angle. Therefore:
\(o = a=9\)
The side labelled "f" is the hypotenuse of the triangle. Therefore:
\(f= 2a = 2 \cdot 9=18\)
Therefore:
o = 9f = 18Angle TLN equals (3X -18)°, angle MZQ equals (5X +14)° and

Parallel lines are lines that always stay the same distance apart and never meet.
Transversal line :
A transversal is a line that crosses two or more other lines.
given,
∠TLN = (3x - 18)°
∠MZQ = (5x + 14)°
∠NLM = y°
Now,
∠MZP + ∠MZQ = 180° (Linear Pair)
∠MZP = 180° - ∠MZQ ...........(I)
again,
∠NLM + ∠TLN =180° ...........(II) (Linear Pair)
As, ∠TLN = ∠MZP (Corresponding Angle)
(3x - 18)° = 180° - ∠MZQ
(3x - 18)° = 180° - (5x + 14)°
3x + 5x = 180° - 14° + 18°
8x = 184°
x = 184 / 8
x = 23°
From (II),
∠NLM + ∠TLN =180°
y° + 3x - 18° = 180°
y = 180 - 3x + 18
= 180 - 3* 23 + 18
= 180 - 69 +18

Find m<1 and m<2 in the following
Applying the alternate exterior angles theorem:
m<1 = 122 degrees.
m<2 = 58 degrees.
What is the Alternate Exterior Angles Theorem?If a transversal intersects two parallel lines, and one angle is formed on the outside of the parallel lines and on one side of the transversal, and another angle is formed on the outside of the parallel lines and on the other side of the transversal, then these two angles are congruent based on the alternate exterior angles theorem.
Thus, we have:
Angle 2 and 58 degrees are alternate exterior angles, therefore:
m<2 = 58 degrees.
Also, angles 1 and 2 form a straight line angle, since a straight line angle is equal to 180 degrees, therefore:
m<1 + m<2 = 180
Substitute:
m<1 + 58 = 180
m<1 = 180 - 58
m<1 = 122 degrees.
