Calculating the magnitude of an angle necessitates knowledge of complementary, additional, and neighboring angles, as well as geometric form attributes. To compute the magnitude of the angle in question, subtract the specified supplementary angle (its value in degrees) from 180. An angle is measured in degrees from 0° to 180° in geometry. The angle’s size is indicated by the number of degrees.

The Pythagorean theorem Let xyz angle = A So, tan(A) = opposite/next => tan(A) = 15/6 As a result, A = tan-1(15/6) => 68.19863 As a result, angle xyz = 68 degrees. I hope this helps. You can also schedule a class for more clarification. Right angles are 90 degrees in length. Obtuse angles are more than 90 degrees.

A convex mirror's generated image is always virtual and situated behind the mirror. The picture is erect and situated at the focal point when the item is far from the mirror.

The radius of curvature is the measurement between the vertex and the center of the curve (represented by R). The sphere from which the mirror was sliced has a radius equal to the radius of curvature. The distance between the vertex of the circle used to create the cylindrical mirror's shape to its center is known as the center of curvature.

In addition, the center of curvature will house the image. The image will be upside-down in this situation. The proportions of the image match those of the object. The image is the same size as the object, actual, and inverted if the object is at the center of the curve.

Integrating this expression, we obtain: −20√4 cosθe−r2 + C, where C is the constant of integration. Therefore, the integral evaluates to this expression.

Using polar coordinates, we have:

20√4 − r cosθ20e−r2 − r sin2θ dr dθ

This simplifies to:

20√4 − r cosθ20e−r2 dr dθ

Now we can integrate:

∫20√4 − r cosθ20e−r2 dr dθ = −20√4 cosθe−r2 + C

Where C is the constant of integration.

This iterated integral can be evaluated by converting to polar coordinates. We first rewrite the integral as: 20√4 − r cosθ20e−r2 dr dθ. Integrating this expression, we obtain: −20√4 cosθe−r2 + C, where C is the constant of integration. Therefore, the integral evaluates to this expression.

Answer: Let x be the length of the original piece of fabric.

We know that:

x - y = length after first cut

(x - y) - 10 = length after second cut

((x - y) - 10) - 5 = length after third cut

Therefore, we can set up the equation:

x - y - 10 - 5 = 35

x - y = 50

To find the original length of the fabric, we can add y to both sides:

x = y + 50

The original length of the fabric is 50 inches + y inches.

We know that the total length cut was 35 inches.

So we can set up the equation:

y + 10 + 5 = 35

y = 20

So the original length of the fabric is 50 + 20 = 70 inches.

We can check the solution by using the equation:

x - y - 10 - 5 = 35

70 - 20 - 10 - 5 = 35

which is true.

Step-by-step explanation:

2W² + 2W = 264  is the equation that an be used to find the width, W, of the porch. The value w = 11 gives the width of the porch, in feet.

The tools that aid in indicating an object's measurements are length, width, and height. We can calculate the volume of geometric shapes using their length, width, and height.

The length of an object or a figure on a planar surface is its longest measurement. The length of the specified object or figure is indicated.

The width of an object or figure on a planar surface is its smallest dimension. It provides the object or figure's width information.

Height is the measurement of an object's vertical distance from a figure or a planar surface.

Given that a rectangular porch has an area of  264 ft²

L × W = 264 ft²

And

W = L/2 - 1

or

L = 2(W + 1)

Substitute the value of L in area Equation

2(W + 1) × W = 264

2W² + 2W = 264

Putting the equation in quadratic formula we get

1. The area of the region enclosed by one loop of the curve r = sin(8theta) is 16π.

2. The area of the region enclosed by one loop of the curve r = 7 cos(3theta) is 28π.

The area of a region enclosed by one loop of a curve is calculated by using a method called the “area under the curve”. This method involves integrating the equation of the curve over one full period (or loop) of the curve. For example, in the case of a curve with equation r = sin(8theta), the area of the region enclosed by one loop of the curve is equal to the integral of r = sin(8theta) from 0 to 2π. This integral evaluates to 16π, which is the area of the region enclosed by one loop of the curve. The same method can be applied to a curve with equation r = 7 cos(3theta) to find the area of the region enclosed by one loop of the curve. In this case, the integral of r = 7 cos(3theta) from 0 to 2π evaluates to 28π, which is the area of the region enclosed by one loop of the curve.

Using the idea of inequality and some simple math calculations, the total number of persons who can visit an amusement park is 4.

Given that a group of friends has a maximum of $160 in this question.

$10.50 is the cost of parking.

The price of each ticket is $32.50.

We must address inequality.

So let's attempt to define inequity.

Inequalities in mathematics describe the connection between two non-equal quantities. Equal does not necessarily mean unequal. When two values are not equal, we typically use the "not equal sign (≠)". However, a number of inequalities are used to compare the numbers and determine whether one is greater than the other.

A relation is called an inequality if two real numbers or algebraic expressions are related by the symbols ">"  "<"  "≥" "≤".

Let's Suppose we have a total of x number of persons.

then the total cost of tickets is 32.5 * x.

cost of parking is $10.50.

So the total cost to visit an amusement park is = 32.5x+ 10.50

Given that the total cost will be no more than $160.

So according to that

32.5x+ 10.50 ≤ 160.

32.5x ≤ 160-10.50

32.5x ≤ 149.5

x ≤ 149.5/32.5

x ≤ 4.6.

The nearest integer will be 4.

The group of friends can have no more than 4 people go to the amusement park.

We can use an inequality to determine the number of people who can go to the amusement park. We know that the group has no more than $160 to spend on parking and admission. We also know that parking is $10.50 and tickets cost $32.50 per person, including tax.

The inequality we can use to determine the number of people who can go to the amusement park is: 10.50 + 32.50x ≤ 160

To solve the inequality, we must first subtract 10.50 from both sides of the equation to isolate variable x. This gives us: 32.50x ≤ 149.50

Next, we must divide both sides of the equation by 32.50 to solve for x. This gives us: x ≤ 4.62

Since x is the number of people who can go to the amusement park, we must round down to the nearest whole number. This gives us: x ≤ 4

Therefore, we can conclude that the group of friends can have no more than 4 people go to the amusement park.

Original cost = $899

Discount = 40% = 0.40

State tax rate = 7.25% = 0.0725

Total amount = Original cost × (1 - Discount) × (1 + State tax)

Total amount = 899×(1 - 40%)×(1 + 7.25%)

Total amount = 899×(1 - 0.40)×(1 + 0.0725)

The total amount that Mikaela spent on the paddleboard is $578.51. The result is obtained by subtracting the discount from the original price and adding the tax.

When we get a discount of a product, the price will get cheaper. The price is subtracted by the discount. When there is a tax, you have to pay for it.

Mikaela purchased a paddleboard with the original price of $899. She got a discount of 40%. The tax rate is 7.25 %. Find the total amount she paid for the paddleboard!

From the information, we get the discount

= 40% × $899

= 0.4 × $899

= $359.6

The tax would be

= 7.25% × $899

= 0.0725 × $899

= $39.11

The total price is

= original price - discount + tax

= $899 - $359.6 + $39.11
