The 4 tests for similar triangles are:-

AAA: Three pairs of equal angles.

SSS: Three pairs of sides in the same ratio.

SAS: Two pairs of sides in the same ratio and an equal included angle.

ASA: Two angles and the side included between the angles of one triangle are equal

What is AAA,SAS,ASA,SSS?

According to the SSS rule, two triangles are said to be congruent if all three sides of one triangle are equal to the corresponding three sides of the second triangle. 

According to the SAS rule, two triangles are said to be congruent if any two sides and any angle between the sides of one triangle are equal to the corresponding two sides and angle between the sides of the second triangle.

According to the ASA rule, two triangles are said to be congruent if any two angles and the side included between the angles of one triangle are equal to the corresponding two angles and side included between the angles of the second triangle.

According to the  AAA rule, "if in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion), and hence the two triangles are identical."

Answer:

The length of the runway =  12090 feet

Step-by-step explanation:

The formula involving the area of a rectangle is

\(A=wl\)

here

Given

Area A = 1,934,400 square feet

Width w = 160 w

Length l = ?

Using the formula

\(A=wl\)

substituting the values

1,934,400 = 160 × l

l = 1,934,400 / 160

l = 12090 feet

Therefore, the length of the runway =  12090 feet

The given equation is \( A(8.7x-8) = 3(2x-1) + 12.8 \). In order to solve this equation, we need to simplify and rearrange it to isolate the variable \( x \).

To solve the equation \( A(8.7x-8) = 3(2x-1) + 12.8 \), we can start by distributing the values inside the parentheses on both sides of the equation. This gives us \( 8.7Ax - 8A = 6x - 3 + 12.8 \).

Next, we can simplify the equation by combining like terms. On the right side, we have \( 6x - 3 + 12.8 \), which simplifies to \( 6x + 9.8 \). Therefore, the equation becomes \( 8.7Ax - 8A = 6x + 9.8 \).

To isolate the variable \( x \), we can move all terms containing \( x \) to one side of the equation and all the constant terms to the other side. This can be done by subtracting \( 6x \) from both sides, resulting in \( 8.7Ax - 6x - 8A = 9.8 \).

Now, we can factor out \( x \) from the left side of the equation, giving us \( x(8.7A - 6) - 8A = 9.8 \).

Finally, we can solve for \( x \) by dividing both sides of the equation by \( 8.7A - 6 \), giving us \( x = \frac{{9.8 + 8A}}{{8.7A - 6}} \).

Area of the sheep pen = 1600feet square

The amount of space occupied by a flat (2-D) surface or form of an object is known as its area.

180 feet of fence were purchased.

The perimeter of a rectangular sheep pen is equal to two times the length plus the width, or two times the length plus 180. One side of the rectangular sheep pen is covered with a barn, which equals the width.

The rectangular sheep pen's covered side:

180 =2 length + width

180 = 2 x80 +width

180 - 160 = width

20= width

Area = l*b = 80*20

Answer:

x=62° y = 92°

Step-by-step explanation:

x° and 118° are same side interior angles.

So,

x+118 = 180

Subtract 118 on both sides,

x = 180 - 118 = 62

x = 62°

Angles inside the triangle are y, 22 and x

x + y + 22 = 180

But , x = 62°

So, 62 + 22 + y = 180

88 + y = 180

Subtract 88 on both sides,

y = 180 - 88 = 92°

Laplace transform of the given DE: Y(s) = [(5 + (s + 2)(s² + 25)) / (s² + 2s)(s² + 25)]

a. To calculate the Laplace transform of the given differential equation, we can apply the transform to each term individually. Using the properties of the Laplace transform, we have:

L{d²y/dt²} = s²Y(s) - sy(0) - y'(0) = s²Y(s) - s

L{dy/dt} = sY(s) - y(0) = sY(s) - 1

The Laplace transform of sin(5t) can be found using the property L{sin(at)} = a/(s² + a²). In this case, a = 5, so:

L{sin(5t)} = 5/(s² + 5²) = 5/(s² + 25)

Putting all the terms together, we can write the Laplace transform of the differential equation as an algebraic equation in the s-domain:

s²Y(s) - s + 2(sY(s) - 1) + 2Y(s) = 5/(s² + 25)

b. Now, let's solve this equation for Y(s):

s²Y(s) - s + 2sY(s) - 2 + 2Y(s) = 5/(s² + 25)

(s² + 2s)Y(s) - s - 2 = 5/(s² + 25)

(s² + 2s)Y(s) = (5/(s² + 25)) + (s + 2)

Y(s) = [(5 + (s + 2)(s² + 25)) / (s² + 2s)(s² + 25)]

Note: The above expression represents the Laplace transform of y(t), denoted as Y(s). To find the solution in the time domain, we would need to take the inverse Laplace transform of Y(s), which is beyond the scope of this calculation.

What is word problem?

A math word problem is a mathematical question that is stated as one sentence or more and asks students to use their arithmetic skills in a "real-life" situation. Therefore, in order for kids to understand the word problem, they need to be familiar with the terminology that goes along with the mathematical symbols that they are used to.

Given that:   quantity negative two thirds times x minus 6 end quantity minus quantity negative 14 plus one sixth times x end quantity

It can be write in mathematical form as,

Simplifying the parenthesis,

\(= -\frac{2}{3}x-6+14-\frac{1}{6}x\\ = 8 - \frac{15}{18}x\\ = 8 - \frac{5}{6}x\\= -\frac{5}{6}x+8\)
