What is the order of the angle from largest to smallest?
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).
What are angles?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).

What are the vertical and horizontal asymptotes for the function f/x )= x2 x 6 x 3 1?
The function given by the question, [tex]f(x) = \frac{x^{2} }{6x+31}[/tex] , the vertical asymptote will be at x = -31/6 and there will be no horizontal asymptote.
What is horizontal asymptote?A horizontal asymptote is a line that guides the graph of a function for x-values that are "far" to the right or left but not on the graph itself. The graph might cross it, but ultimately, for sufficiently big or sufficiently low values of x, the graph would approach the asymptote without hitting it. A slant asymptote has a specific instance known as a horizontal asymptote.
What is vertical asymptote?A vertical line that directs the function's graph but is not actually a part of it is called a vertical asymptote. Because it appears at an x-value outside of the function's scope, the graph can never cross it. There may be several vertical asymptotes for a given function.
Solve 6x + 31 = 0 for x to obtain the vertical asymptotes of the function x2/(6x+31). The vertical asymptote is x = -31/6 because x = -31/6 is the solution. Because the degree of the numerator is larger than the degree of the denominator by 2, the function has no horizontal asymptotes (1).

The table shows a linear relationship between x and y. What is the rate of change of y with respect to x?.
The rate of change of y with respect to x is the slope of the line which is 2.
To find the slope of a line, you can use the following formula:
slope = (y2 - y1)/(x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
For example, if the table shows the following values for x and y:
[tex]\boxed{x | y}\\\boxed{0 | 0}\\\boxed{2 | 4}\\\boxed{4 | 8}[/tex]
The slope of the line can be calculated by finding the difference in the y-values between two points and dividing it by the difference in the x-values between those same two points. For example, the slope between the points (0,0) and (2,4) would be calculated as follows:
slope = (4 - 0)/(2 - 0) = 4/2 = 2
Therefore, the rate of change of y with respect to x is 2.
The slope of a line represents the rate of change of one variable (y) with respect to another variable (x). In other words, it tells us how much y changes for every unit change in x. In this case, the slope of the line is 2, which means that for every unit increase in x, y increases by 2 units. This is a linear relationship because the slope is constant, meaning that the rate of change is always the same.

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.
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.

Answer: 4 2/3
Step-by-step explanation:
14/3 is an improper fraction. Let's take the numerator and divide it by the denominator.
Divide 14 by 3. The quotient digit is 4.
Multiply the quotient digit 4 by the divisor 3.
Subtract 12 from 14.
The result of 14 divided by 3 is 4 with a remainder of 2.
Thus, 14/3 as a mixed number can be written as 4 2/3.
14/3 as it can't further cut out.
Because in a mixed number it is 4 2/3. This can be expressed as a fraction by multiplying the whole number (4) by the denominator (3) and adding it to the numerator (2), giving a fraction of 14/3.

Area of irregular shapes
Answer:
The area of the irregular shape is 268.8.
Step-by-step explanation:
To find the area of an irregular shape, we first have to break it into common shapes, here, in this case, we will break it into a rectangle with sides 14 and 8 and a triangle with a base length equal to 14 and the opposite angle to the base is equal to 32°.
The area of the rectangle is equal to the product of the side lengths which is equal to [tex]14*8=112[/tex]. Therefore [tex]A_{1} =112[/tex].To find the area of the triangle we have to find the height of the triangle. Since [tex]tan32=\frac{14}{Height}[/tex], this implies height is equal to [tex]\frac{14}{tan32}=22.40[/tex]. Now the are of triangle is equal to product of half times bease times height .
