The AA criterion for triangle similarity states that if two triangles have two pairs of congruent angles, then the triangles are similar.
What is a triangle similarity criterion?
According to the Angle-Angle (AA) criterion, two triangles are considered comparable if "two angles of one triangle are respectively equivalent to two angles of another triangle."
What distinguishes AA similarity from AAA similarity?
The total number of angles in a triangle is 180. Therefore, the third angle of a triangle will automatically become equal if two of its angles are equal. Triangles are related because of the AA resemblance. Three angles should equal the other triangle in AAA.Learn more about Angle-Angle-Side (AAS)

The tangent ratio for the ΔABC is tanФ = 1.
What is defined as the trigonometric ratios?The values of all trigonometric functions derived from the ratio of sides inside a right-angled triangle are defined as trigonometric ratios. The trigonometric ratios of any acute angle are the ratios of the sides of such a right-angled triangle with respect to that acute angle.Some of the trigonometric ratios are-
sin = perpendicular/hypotenusescos = base/hypotenusestan = perpendicular/basecosec = 1/sinsec = 1/coscot = 1/tanFor the given right angles triangle ABC.
The sides AC = CB = 15
As, the angle ACB is the right angle i.e, ∠ACB = 90°, so, AB is the hypotenuses of the triangle.
For finding the value of tangent ratio;
tan = perpendicular/base
tan B = AB/ CB
tan B = 15/15
tan B = 1/1
tan B = 1
Thus, the value of tangent ratio = 1.

Solve without graphing. Find the slope and the y-intercept for the graph of each equation in the given system. Use this information (and not the equations' graphs) to determine if the system has no solution, one solution, or an infinite number of solutions.
For equation (1), we get the Slope as 3 / 4 and y intercept as - 9 and for equation (2), we get the Slope as 3 / 4 and y intercept as - 4.
We are given 2 equations:
y = 3 / 4 x - 9 ...(1)
and y = 3 / 4 x - 4 ... (2)
Slope for equation (1) will be
slope = m1 = 3 / 4
Slope for equation (2) will be
Slope = m2 = 3 / 4
Y intercept for equation (1) will be:
= - 9
Y intercept for equation (2) will be:
= - 4
Also, since the Slope of equation are equal, so, it has no solutions as they are parallel to each other.
Therefore, for equation (1), we get the Slope as 3 / 4 and y intercept as - 9 and for equation (2), we get the Slope as 3 / 4 and y intercept as - 4.

If P(A | B) is the same as P(A) , and P(B \mid A) is the same as P(B) , what can be said about the relationship between events A and B ?
When P(A | B) = P(A) and P(B ∩ A) = P(B). Then, the given events A and B are independent events.
What is defined as the independent events?Independent events are those where the occurrence is unrelated to any other event.
For example, suppose we toss a coin as in air and the result Head, then we throw the coin again and get the result Tail. Both events occur independently of one another in both cases.Now, as for the given question.
There are two events given as A and B.
The probability of occurrence of event A is P(A).
The probability of occurrence of event B is P(B).
The occurrence of the event A when B is already happened is denoted by P(A | B).
The intersection of events A and B are given as; P(B ∩ A).
Now, it is given in the question that;
P(A | B) = P(A) and P(B ∩ A) = P(B)
And, we already know that, the formula of the conditional probability for event A when event B has already occurred is;
P(A | B) = P(B ∩ A)/P(B)
This can also be written as;
P(B ∩ A) = P(A | B).P(B)
Now, P(A | B) = P(A), replace in the obtained equation.
P(B ∩ A) = P(A).P(B)

In horse racing, a trifecta is a bet that the first three finishers in a race are selected, and they are selected in the correct order. Does a trifecta involve combinations or permutations? explain.
In horse racing, a trifecta, which is a bet that the first three finishers in a race are selected, and they are selected in the correct order, involves selection done in permutation.
Permutation is the method of selecting or arranging objects or numbers in order. It is used when the order or sequence of the elements selected is important. The number of permutations of n objects taken r at a time is determined by the following formula: P(n , r) = n!
On the other hand, combination is the method of selecting or arranging objects or numbers from a group of objects or numbers where order does not matter. The number of combinations of n objects taken r at a time is determined by the following formula: C(n , r) = n!/[r!(n - r)!]

Use each recursive definition to write an explicit formula for the sequence. a₋₁ = 1, a n =a n ₋₁ +4
The explicit formula for the given sequence is a(n) = 1 + 4(n - 1).
What is termed as recursive definition?A recursive function is one that iterates or uses its very own previous term to determine subsequent terms, resulting in a series of terms.
The recursive formula for an arithmetic sequence is as follows.
a(1) = 1 and a(n) = a(n - 1) + 4.
Remember that this formula provides us with two types of data.
1 is the first term.Add 4 to obtain any term out of its previous term. To put it another way, this same common difference is 4.Let's look for a formal formula again for sequence.
Remember that we can use the standard explicit form to represent a sequence in which the first term is A & common difference is B: A + B(n - 1).As a result, the sequence's explicit formula is a(n) = 1 + 4(n - 1).Thus, by the use of recursive definition, the explicit formula for the sequence is a(n) = 1 + 4(n - 1).

The length of a rectangle is four more than double the width. If the perimeter is 80 inches, find the dimensions.
The width is inches.
The length is inches.
Answer: width = 12 inches
length = 28 inches
Step-by-step explanation:
l = 4 + 2w
Perimeter = 2 ( l + w )
80 = 2 ( 4 + 2w + w )
80 = 2 ( 4 + 3w )
80 = 8 + 6w
80 - 8 = 6w
72 = 6w
w = 72 / 6
width = 12 inches
length = 4 + 2 (12)
= 4 + 24
= 28 inches

Perimeter = 2 ( 28 + 12 )

The expression "quantity negative three and one third times n plus one sixth end quantity plus quantity one and three sixths times n minus three twelfths end quantity" or (-3 1/3n + 1/6) + (1 3/6n - 3/12) is equivalent to "negative eleven sixths times n minus one twelfth" or -11/6n - 1/12.
An algebraic expression is a number, variable, or the combination of both and operational symbols.
To determine the equivalent of the expression "quantity negative three and one third times n plus one sixth end quantity plus quantity one and three sixths times n minus three twelfths end quantity" or simply (-3 1/3n + 1/6) + (1 3/6n - 3/12), combine all like terms and perform necessary operations.
(-3 1/3n + 1/6) + (1 3/6n - 3/12)
⇒ -3 1/3n + 1 3/6n + 1/6 - 3/12
⇒ (-3 1/3 + 1 3/6)n + 1/6 - 3/12
⇒ (-10/3 + 9/6)n + 2/12 - 3/12

Answer:
Perimeter: 2(7+12), 2*7+2*12, 7+12+7+12
Area: 7*12, 7*10 + 7*2
neither: 7+12
Step-by-step explanation:
perimeter is like if you want a fence all the way around your property and your yard is 7x12 feet. In that case you could use the first option because you have to count the sides and add them up. If it’s a rectangle then there are 2 12’s and 2 7’s so the first one would work. The fourth one also uses distribution. The Fourth and first one are pretty much the same and have the same answer so the fourth one would work for perimeter.
Another way to do perimeter is to instead of multiplying, is to add the sides. 7+12+7+12 is basically 7 times 2 plus 12 times 2 (the fourth ne) and the answer is still correct so this one works too,
For area you times one of the dimensions by the other so 7*12 would work for area.
7*10 + 7*2 would also work because that uses the distributive property and that’s 70 + 14 which is 84 which is still the same answer.
The only one that falls under neither is the fifth one. 7+12 is half of the perimeter because it only adds two of the sides together and has n multiplying so it’s not area either.

Each sequence has eight terms. Evaluate each related series. -3.5,-1.25,1,. . . . . . , 12.25
An arithmetic progression (AP) is a sequence of numbers ordered such that the difference between any two consecutive numbers is a constant value. Also called arithmetic sequence. For example, the sequence of natural numbers: 1, 2, 3, 4, 5, 6, … is an arithmetic sequence in which the common difference between two consecutive terms (e.g., 1 and 2) is 1 (2 - 1) ... It can be seen that the tolerance of two consecutive terms is equal to 2, even for odd and even numbers.
First term a=-3.5,
Common difference d=2.25,
Number of terms n=8
Solution:
Here first term a=-3.5,
Common difference d=2.25
We know that,
f(n)=a+(n-1) d
f (8)=-3.5+(8-1)(2.25)
=-3.5+(15.75)
=12.25
We know that,
Sn=n2[2a+(n-1)d]
∴S8=82⋅[2(-3.5)+(8-1)(2.25)]
=4⋅[-7+(15.75)]
=4⋅[8.75]
=35
Hence, 8th term of the given series is 12.25 and sum of first 8th term is 35.
