Which pair of triangles can be proven congruent by SAS? 2 identical triangles are shown. The triangle is reflected across a line to form the second triangle. 2 identical triangles are shown. The triangle is rotated 90 degrees to form the second triangle. 2 identical triangles are shown. The triangle is reflected across a line and then rotated to form the second triangle. 2 identical triangles are shown. The triangle is rotated up and to the left 90 degrees to form the second triangle.
Answer:
its the third option
Step-by-step explanation:
the one with 2 rings on the second longest angle 2 lines on longest side one side and 1 line on the shortest side
All the described pairs of triangles that are reflected, rotated, or both, can be proven congruent by the SAS postulate because such rigid transformations preserve the congruency of sides and angles.
Explanation:To determine which pair of triangles can be proven congruent by the SAS (Side-Angle-Side) postulate, we look for two sides of a triangle and the included angle that are congruent to two sides and the included angle of another triangle. When a triangle is reflected across a line, rotated 90 degrees, or both reflected and rotated, it maintains its size and shape, thus the corresponding sides and angles remain congruent.
A reflection or rotation (including a combination of both) is a type of rigid transformation which preserves the size and shape of figures. Hence, all the given pairs of triangles can be proven congruent to the original triangle through the SAS postulate, as rigid transformations do not alter the congruity of sides and included angles.

This cuboid is made from centimetres cubes
write down the volume of the cuboid
using the image below
the cuboid is then split in half
Answer:
72 for q1 and q2 is 18
Step-by-step explanation:
Final answer:
To find the volume of a cuboid, multiply its length, width, and height. If made of 1 cm cubes, the volume is the number of these cubes. Halving the cuboid evenly would halve its volume.
Explanation:
To calculate the volume of a cuboid, you multiply the length, width, and height of the cuboid. The question doesn't provide specific dimensions, but assuming that you have them, the formula you would use is Volume (V) = length × width × height. If the cuboid consists of centimeter cubes, each with a side length of 1 cm, the volume in cubic centimeters will be equal to the number of these small cubes.
For example, let's say the dimensions of the cuboid are 5 cm × 3 cm × 4 cm. The volume would then be calculated as V = 5 cm × 3 cm × 4 cm = 60 cm³.
If the cuboid is split in half, the resulting two pieces would each have a volume that is half of the original total volume, assuming the split is made evenly.
A coffeepot contains 1 1⁄2 quarts of coffee. After Tonya pours an equal amount of coffee into two cups, 3 1⁄2 cups of coffee remain in the pot. How much coffee did Tonya pour into each cup?
Answer:
1.25cups(8oz/1cup)=10 ounces
Step-by-step explanation:
we convert 1 1/2 quarts to cups. There are 4 cups in a quart:
1 1/2 quarts= 3/2 quarts (4 cups/ 1 quart)= 6 cups
Amount poured out:
6 cups- 3.5 cups= 2.5 cups
Amount poured in each cup:
2.5/2=1.25 cups

Given:
(a) To determine the inequality for x for the given line.
Inequality:
Since, from the figure, it is obvious that the number line contains an open circle at the point 3.
This means that the end value 3 is not included in the interval.
Hence, the inequality can be written as [tex]x<3[/tex]
Thus, the inequality for x is [tex]x<3[/tex]
(b) Given that [tex]2<y<6[/tex] where y is an integer.
We need to determine the possible values of y.
Values of y:
The values of y lie between 2 to 6. Since, the inequality is strictly lesser than, it does not contain the end value.
Therefore, the possible values of y are 3,4,5
(3) Given the inequality [tex]3 x+7>x+19[/tex]
We need to solve the inequality.
Solution:
[tex]3 x>x+12[/tex]
[tex]2 x>12[/tex]
[tex]x>6[/tex]
Thus, the solution of the inequality is [tex]x>6[/tex]

An airplane is flying at an altitude of 6 miles (approximately 32,000 feet) toward a point directly above where you are standing. If you are standing x miles away from a spot that is perpendicular to the plane, what is the equation that relates the angle as a function of x? Then, using that equation, solve for when x is 2 miles.
Answer:
angle = arc tangent(6/x)
for x=2 -> angle = 71.565°
Step-by-step explanation:
To find the relation of the distance x and the angle of elevation that you are seeing the airplane, we should use the tangent relation of the angle. The opposite side of the angle is the altitude of the airplane, and the adjacent side of the angle is the distance x.
So we have that:
tangent(angle) = 6/x
angle = arc tangent(6/x)
If we have the value of x = 2, the angle will be:
angle = arc tangent(6/2) = arc tangent(3)
angle = 71.565°

To express 123,000,000 as a multiple of a power of 10, we identify it as 1.23 x 10^7.
The question asks to express 123,000,000 as a multiple of a power of 10. To do this, we need to understand how exponents of 10 work. The exponent tells us how many zeros are added to the right of 1 to create the number. For instance, 10^2 equals 100 because there are two zeros.
In the case of 123,000,000, we count the zeros following the initial digit(s). There are 7 zeros. Therefore, we can express 123,000,000 as 1.23 x 10^7. Here, 1.23 is the coefficient (a value greater than or equal to 1 but less than 10), and 10^7 indicates that the decimal point in 1.23 is moved 7 places to the right to get the original number, 123,000,000.
This method of notation is commonly used in scientific notation, which simplifies large numbers by expressing them as a multiple of a power of 10. It's a useful way to work with very large or very small numbers efficiently.

y = x - v/b ; solve for x
Answer:
x = y + v/b
Step-by-step explanation:
You can solve for x by adding v/b to both sides since that is what will isolate x the quickest and that is what you want to do when you need to solve for something.
By adding v/b to both sides, you will end up with x=y+v/b and that’s your answer!

To find the value of x in a similar triangle question, you need to identify the corresponding sides and use their ratio to solve for x. In this case, PQR is similar to SQT, and the corresponding sides are PQ and SQ, PR and ST, and QR and QT. The ratio of the side lengths can be used to find the value of x.
Explanation:If two triangles are similar, it means that their corresponding angles are equal, and the ratio of their corresponding side lengths is constant. In the given question, PQR is similar to SQT. To find the value of x, we need to identify the corresponding sides and find the ratio between them. Let's assume that the corresponding sides are PQ and SQ, PR and ST, and QR and QT. The ratio of the side lengths can be written as:
x / (p + q) = PQ / SQ. Using this ratio, we can solve for x by multiplying both sides of the equation by (p + q):
x = (PQ / SQ) * (p + q)

A jewelry box has a length of 3 1/2 units, a width of 1 1/2 units, and a height of 2 units. What is the volume of the box in cubic units?
Answer:
10 1/2 or 10.5
Step-by-step explanation:
V=l*w*h
Volume = length * width * height
length = 3 1/2 = 3.5
width = 1 1/5 = 1.5
height = 2
input the values V = 3.5 * 1.5 *2
multiply the first two numbers 3.5 * 1.5 = 5.25
multiply the first result by the third number 5.25 * 2 = 10.5
Volume = 3.5 * 1.5 *2= 5.25 * 2 = 10.5 = 10 1/2
3 1/2 * 1 1/5 * 2 = length * width * height = Volume = 10 1/2
Volume = 10 1/2
