Two similar triangles are shown below:
Two triangles are shown. The sides of the triangle on the left are marked 4, 5, 6. The sides of the triangle on the right are marked as 3, 2, and 2.5. For the triangle on the left, the angle between sides marked 6 and 5 is labeled as a, marked by a double arc, and the angle between the sides marked 6 and 4 is labeled as b, marked by a single arc. The third angle is marked by a triple arc. For the triangle on the right, the angle between sides marked 2 and 3 is labeled as c and the angle between the sides marked 2.5 and 3 is labeled as d, marked by a double arc. The angle between the sides 2 and 2.5 is labeled as e, marked by a triple arc, and it is also the angle on the top vertex of this triangle.
Which two sets of angles are corresponding angles? (4 points)
Group of answer choices
∠a and ∠e; ∠b and ∠c
∠a and ∠c; ∠b and ∠d
∠a and ∠e; ∠b and ∠d
∠a and ∠d; ∠b and ∠c
Step-by-step explanation:
the 2 triangles are similar.
that means their corresponding angles are equal, and their side lengths (and heights and so on) have all the same constant scaling factor.
so, we see that the side with the length 6 must corresponds to the side with the length 3 (factor 1/2).
as then the side with the length 5 corresponds to the side with the length 2.5, and the side with the length 4 corresponds to the side with the length 2 (all have the same factor 1/2).
a is the angle between 6 and 5 (the 2 longest sides).
the angle between the 2 longest sides in the smaller triangle (3 and 2.5) is d.
so, a and d correspond.
b is the angle between 6 and 4 (the longest and the shortest side).
the angle between the corresponding sides 3 and 2 is c.
so, b and c correspond.
therefore, the 4th and last answer choice is correct.

Rigid transformations are used to map the triangle formed by A(0,0),B(3,0),C(3,4) to triangle A ′ B ′ C ′ . If the coordinates of A ′ , B ′ And C′ are A ′ (−2,1) and B ′ (−2,−2) , what are the two possible answer for C’
The possible coordinates of the point C are : (-6,-2) and (2,-2).
A stiff transition called a rotation involves turning the item around a center point. The direction is changed, but the shape is still oriented in the same way. You can spin a form in any direction. A 180 degree rotation of the triangle is made around point C. A rigorous transition like this one may be seen here.
Rotation and translation are the only two elements of a rigid transformation. It does not alter the size or shape of an input object, nor does it involve reflection.

What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ log₅ (1/25)
Now,
Solve the expression as;
⇒ log₅ (1/25)
Since, log (a/b) = log a - log b
Hence,
⇒ log₅ (1/25) = log₅ 1 - log₅ 25
Since, log 1 = 0
⇒ log₅ (1/25) = 0 - log₅ 25
⇒ log₅ (1/25) = - log₅ 5²
Since, log a² = 2 log a
⇒ log₅ (1/25) = - 2 log₅ 5
Since, log₅ 5 = 1
⇒ log₅ (1/25) = - 2 x 1
⇒ log₅ (1/25) = - 2
Thus, The value of the expression will be;

What is meant by an expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. Expressions have the following structure: (Number/variable, Math Operator, Number/variable).
Given: [tex]$275000=\frac{3001-\left(1+\frac{0.038}{12}\right)^{(-12 t)}}{\left(\frac{0.038}{12}\right)}$$[/tex]
Multiply both sides by 0.038 / 12, we get

Simplifying the above equation, we get
[tex]$\frac{5225}{6}=3001-\left(1+\frac{0.038}{12}\right)^{-12 t}$$[/tex]
Add [tex]$\left(1+\frac{0.038}{12}\right)^{-12 t}$[/tex] to both sides

Simplifying the above equation, we get
[tex]$\frac{5225}{6}+\left(1+\frac{0.038}{12}\right)^{-12 t}=3001$$[/tex]
Subtract 5225 / 6 from both sides
[tex]$\frac{5225}{6}+\left(1+\frac{0.038}{12}\right)^{-12 t}-\frac{5225}{6}=3001-\frac{5225}{6}$$[/tex]

Answer:
x = 8.3
Step-by-step explanation:
We look at the final place of the decimal to round, in this case the thousandths place (underlined)
8.27
If the final place of the decimal is greater than or equal to 5, we round up the decimal to the left, otherwise we round down.
Because 7 > 5, round 2 up to 3, therefore giving 8.3
Answer:
Your answer is 8.3!
Step-by-step explanation:
Step 1: Locate and underline the tenths place (2) then look at the digit to the right (7):
8.27
Step 2: In this case, the digit to the right (7) is 5 or above. So, we add 1 to the tenth place (2). The digit(s) after the (2) are replaced by zeros (or dropped). Thus, we get 8.3 as the answer.
