Answer:

-2/3

Step-by-step explanation:

The distance between the points (2, 4) and (2, -8) on the coordinate plane is 12 units.

The two-dimensional geometric system of a coordinate plane, also called a Cartesian plane, is used to plot and find points using a pair of numerical coordinates.

The formula for calculating distance between two locations in a two-dimensional coordinate plane is as follows:

Distance = [tex]\sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)[/tex]

where [tex](x_1, y_1)\; and\; (x_2, y_2)[/tex] are the coordinates of the two points.

Using the given points:

Point 1: (2, 4) with [tex]x_1 = 2 \;and \;y_1 = 4[/tex]

Point 2: (2, -8) with [tex]x_2 = 2 \;and\; y_2 = -8[/tex]

Putting these values into the distance formula, we get:

Distance = [tex]\sqrt((2 - 2)^2 + (-8 - 4)^2)[/tex]

Simplifying further:

Distance = [tex]\sqrt(0^2 + (-12)^2)[/tex]

Distance = [tex]\sqrt(0 + 144)[/tex]

Distance = √144

Distance = 12

Step-by-step explanation:

I got it wrong by an expert verified answer

The value of angles x,  ∠DEA, and ∠AEB are 14.5, 39.5, and 140.5 degrees respectively.

An angle in Euclidean geometry is composed of two rays that share a common terminal and are known as the angle's sides and vertices, respectively. In the plane where they are positioned, two rays can create angles. When two planes overlap, angles are also created. These are the so-called dihedral angles. The angle formed by the rays that are perpendicular to the two intersecting curves at the point of junction is another property of intersecting curves. The length of an angle or rotation can also be described using the word angle.

Calculations:

Supplementary angles are angles that sum up to 180degrees.

We can see that:

m<DEA + m<AEB = 180

x+25+9x+10 = 180

10x + 35 = 180

10x = 180 - 35

10x = 145

x = 145/10

x = 14.5

Get  ∠DEA

∠DEA = x + 25

∠DEA = 14.5 +25

∠DEA = 39.5 degrees

Get ∠AEB:

∠AEB = 9x+10

∠AEB = 9(14.5) + 10

∠AEB = 130.5 + 10

∠AEB = 140.5 degrees

Based on the division of 6 and 2 over 5 by  negative 4 and 1 over 3, the result would be negative 1 and 31 over 65.

The operation required is to divide 6 and 2 over 5 by  negative 4 and 1 over 3.

As a math expression, this can be shown as:

= 6²/₅ ÷ -4¹/₃

First, make them improper fractions:

= 32/ 5 ÷ -13/3

This can be converted to multiplication as:

= 32/ 5 x -3/13

= 96 / 65

Step-by-step explanation:

Two non vertical lines have slopes m₁ and m₂ ​, respectively. The lines are parallel if "m₁ = m₂" and the "y-intercepts" are unequal; the lines are perpendicular if m₁ = 1/m₂.

The slope of a line is a measurement of its steepness and direction.

The slope of a line formula computes the "vertical change" to "horizontal change" ratio between two distinct points along a line.

Some key features regarding the slopes of the lines are-

1. Slope of Parallel Lines:

A set of parallel lines always has the same inclination angle. Assume we possess two parallel lines l1 and l2 in the reference plane, inclined at angles θ1  and θ2 with the x-axis, respectively, such that the, θ2 = θ1.

m1 = m2

Therefore, the slopes of the two given parallel lines are equal.

2. Slope of Perpendicular Lines:

A pair of perpendicular lines everytime form a 90 angle. Imagine we have two perpendicular lines l2 and l1 in the coordinate plane, inclined at angles θ1 and θ2 with the x-axis, respectively, so that the provided angles follow the external angle theorem, θ2 =  θ1 + 90.

m1 = tan θ1

m2 = tan (θ1 + 90º) = - cot θ1

m1 × m2 = -1

Therefore, the product of slopes of two given perpendicular lines is equal to -1.

It should be noted that while Euclidean geometry wants to understand the geometry of flat, two-dimensional spaces, the non-Euclidean geometry studies curved, rather than flat, surfaces.

Euclidean geometry, often known as Euclid's geometry, is the study of geometry based on concepts like points, lines, and planes of flat spaces that are not yet defined. It is, in other words, the study of geometrical shapes, including solid and plane shapes, and how these shapes relate to one another in terms of lines, points, and surfaces.

Any geometry that is not the same as Euclidean geometry is considered non-Euclidean geometry. It should be noted that although Euclidean geometry is useful in many fields, in some cases, non-Euclidean geometry is vital as well.
