Obtuse angles, right angles (90 degrees), and acute angles are the three sorts of angles that we can distinguish in order from largest to smallest (smaller than a right angle).

In Euclidean geometry, an angle is made up of two rays that share a terminal and are referred to as the angle's sides and vertices, respectively. Angles can be formed by two rays in the plane where they are placed.

Additionally, when two planes overlap, angles are created.

Dihedral angles are what they are called.

The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation.

A geometrical shape called an angle is created by connecting two rays at their termini. In most cases, an angle is expressed in degrees.

Order of angles from largest to smallest: obtuse angles are the three types of angles that we can recognize (larger than a right angle), Right angles (90 degrees), and acute angles (smaller than a right angle).

Therefore, the order of angles from largest to smallest: obtuse angles are the three types of angles that we can recognize (larger than a right angle), Right angles (90 degrees), and acute angles (smaller than a right angle).

The required median of the given data set is 8.

Finding the middle number requires sorting all the data points and choosing the center one (or if there are two middle numbers, taking the mean of those two numbers).

Example: When the numbers are arranged (1, 4, 7), the number 4 lies in the middle, making it the median of 4, 1, and 7.

So, we have the data:

4, 8, 10, 5, 9

Arrange in ascending order as follows:

What is answer parallel line?

In geometry, parallel lines can be defined as two lines in the same plane that are at equal distance from each other and never meet. They can be both horizontal and vertical.

Parallel lines are two lines in the same plane that are equal distance apart and never intersect.

Real-world parallel line examples include railroad tracks, sidewalk edges, street markings, zebra crossings, the surface of pineapple and strawberry fruit, staircases and railings, and so on.

Parallel lines are lines in a plane that never meet, no matter how far they are extended. The distance between the parallel lines is constant because they never meet.

Answer:

The solution on a graph is the point where two lines interesect

Step-by-step explanation:

When constructing an angle bisector using a compass, all three arcs do not need to have the same radius.

To construct an angle bisector, you first place the point of the compass on one of the angle's vertices and draw an arc that intersects both sides of the angle. Next, you place the point of the compass on the other vertex of the angle and draw another arc that also intersects both sides of the angle. Finally, you draw a straight line through the point where the two arcs intersect, which will bisect the angle.

The radius of the compass does not affect the construction of the angle bisector, as long as the compass is set to a radius that is large enough to intersect both sides of the angle at some point. As long as the arcs intersect, the angle bisector can be accurately constructed, regardless of the radius of the arcs.

The complete question is:-

When constructing an angle bisector, the compass must be used to make three arcs. Do all three arcs need to have the same radius? Explain.

- Yes, because then the marks are equidistant from each other.

- Yes, because you need the points of intersection of the angle and arcs to form a parallelogram.

- No; the second two arcs must have the same radius but it can be different from the first.

- No; any three radii will work.

The greatest product that can be obtained by multiplying two of these 36 integers is; 306

We are told that when 36 consecutive integers are added, the product is -18.

Now, the sequence for these integers would be;

x, (x + 1), (x + 2), (x + 3),......(x + 35)

Now, since the addition of these integers gives a negative number, then it suggests to us that the sequence starts with a negative integer and then ends with a positive integer.

Thus, we have;

x + (x + 1) + (x + 2) +(x + 3) + (x + 35) = -18

The formula for sum of an arithmetic sequence is;

Sₙ = (ⁿ/₂)(2a + (n - 1)d)

where a is first term and d is common difference

Thus;

-18 = (36/2)(2x + (36 - 1)1)

-18 = 18(2x + 35)

-18/18 = 2x + 35

2x + 35 = -1

x = -34/2

x = -17

Thus;

The first term = -17

Last term = -17 + 35 = 18

Thus, the greatest product that can be obtained  = 18 * 17 = 306

Here we have given that the function is [tex]\sum\frac{(-1)^n\pi^{2n}}{4^{2n}(2n)!}[/tex]

And we need to find the sum of series by using the Maclaurin series as

Now, the sum of series is calculated as,

=>f(n) =  [tex]\sum\frac{(-1)^n\pi^{2n}}{4^{2n}(2n)!}[/tex]

When we put the value on n = 0, then we get,

=> f(0) = [1 x 3.14]/1] =  3.14

Now, we have to put the value of the function, the value of x as 1,

Then we get,

=> f(1) = [-1 x 9.8596] / [16 x 2]

=> f(1) = -0.308

And then we have to put the value of function for the value of x as 2,

Then we get,

=> f(2) = [1 x 30.959] / [64 x 24]

=> f(2) = 0.0201

This discriminant is the defining factor of the nature of the roots.

Now, here arise three cases-

(i) If (b^2 - 4ac) > 0, the roots are real and distinct .

(ii) If (b^2 - 4ac) = 0 , the roots are real and equal.

(iii) If (b^2 - 4ac) < 0 , the roots are not real and they are imaginary i.e. they are complex in nature and of the form a+ib.

Step-by-step explanation:

⭐What is an angle bisector?

Thus, ∠MGN ≅ ∠NGO.

To solve for ∠MGN and ∠NGO, we need to:

1. Create an equation about their relationship:

If ∠MGN ≅ ∠NGO, then...

[tex]5x-6 = 11x -42[/tex]

2. Solve for "x":

[tex]5x - 6 = 11x -42[/tex]

[tex]42 - 6 = 11x - 5x[/tex]

[tex]36 = 6x[/tex]

[tex]6 = x[/tex]

3. Substitute "x" back into the equations to find the angle measures:

[tex]< MGN = 5x - 6[/tex]

[tex]< MGN = 5(6) - 6[/tex]

[tex]< MGN = 30 - 6[/tex]

[tex]< MGN = 24[/tex]

❗❗❗At this point, you could write that ∠MGN and ∠NGO = 24°, as they are congruent, but you should still substitute "x" into  ∠NGO to make sure "x" is correct.❗❗❗

[tex]< NGO = 11x - 42[/tex]

[tex]< NGO = 11(6) - 42[/tex]
