We can construct a 30-degree angle by bisecting a 60-degree constructed angle.
By following the given steps we can create a 30-degree angle,
Use a straightedge to create a segment of a line. Label the ends of it. We will refer to them as points A and B in our design.The drawing compass needle should be positioned on point A and adjusted to meet point B. Draw an arc high above the line segment, starting at point B. Move the needle to point B without changing the compass.Make an arc that crosses the first arc swing upward.Create a line segment from point A all the way up to the junction of the two arcs using the straightedge.Mark the new terminus of that line segment as Point D. The angle ∠ABD constructed is a 60-degree angle.Move the needle arm toward one of the rays' points without altering the compass. On the inside of the angle, swing an arc.The needle arm should be moved to the opposite ray's point without adjusting the compass. Draw an arc inside the angle.Use a straight line to connect the intersection of the two arcs with Point B of the 60° angle. That line segment is an angle bisector of the angle ABD, yielding two 30° angles.Read more questions about Triangles and angles from:

what’s the perimeter?
The perimeter of a triangle Park shown on the rate is 13 X -7 what is the missing length
Answer:
The length of the missing side is 7x-5
Step-by-step explanation:
Here, we want to get the value of the missing length
Mathematically, the perimeter of a triangle can be obtained by adding the lengths of its sides
So by subtracting the sum of the lengths of the two given sides from that of the perimeter, we get the length of the third side of the triangle
mathematically, we have this as;
13x-7 -(4x + 2 + 2x-4)
13x-7 - (4x + 2x + 2-4)
= 13x-7 - (6x -2)
= 13x -7 -6x + 2
= 13x-6x -7 + 2
= 7x -5
Suppose the total area is represented by the equation x^2+14x+24. If the area 1 is x^2 square units and area IV is 24 units, what must be true about area II and area III.
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Total = x^2 + 14x + 24[/tex]
[tex]Area\ I = x^2[/tex]
[tex]Area\ IV = 24[/tex]
Required
True about area II and III
The question is incomplete; so, I will answer using general knowledge.
If the total area is:
[tex]Total = x^2 + 14x + 24[/tex]
And there are 4 areas, then;
[tex]Total = Area\ I + Area\ II + Area\ III + Area\ IV[/tex]
Rewrite as:
[tex]Total = Area\ I + Area\ IV+ Area\ II + Area\ III[/tex]
This gives:
[tex]x^2 + 14x + 24 = x^2 + 24+ Area\ II + Area\ III[/tex]
Collect like terms
[tex]x^2 -x^2 + 14x + 24 -24= Area\ II + Area\ III[/tex]
[tex]14x = Area\ II + Area\ III[/tex]
Rewrite as:
[tex]Area\ II + Area\ III = 14x[/tex]
So, the sum of areas III and IV must be 14x

If you apply the changes below to the linear parent function ,f(x)=|x| over the x-axis what is the equation to the new function
Answer:
Answer: A. G(x)= ax=y= - f(x) is flip over x-axis. Therefore, f(x) =14x would become f(x) =-14x. Therefore, final transformed function f(x)=-14x is vertically stretch by a factor of 14 and flip over the x-axis.

Write an expression, in its simplest form, for the volume of this cuboid
Answer:
[tex]V=10x^2+35x+15[/tex]
Step-by-step explanation:
Given that,
Length = (2x+1)
Width = (x+3)
Height = 5
We need to find an expression for the volume of this cuboid . The formula for the volume of cuboid is given by :
[tex]V=lbh[/tex]
So,
[tex]V=(2x+1)\times (x+3)\times 5\\\\=(2x+1)\times (5x+15)\\\\=10x^2+30x+5x+15\\\\=10x^2+35x+15[/tex]
So, the volume of this cuboid is equal to [tex]10x^2+35x+15[/tex].

Answer:
∠e = 105° because ∠e and the 105° angle are vertically opposite angles
∠h = 75° because ∠h and the 105° angle are supplementary angles
∠f = ∠h = 75° because ∠f and ∠h are vertically opposite angles
∠c = 105° because ∠c and the 105° are corresponding angles
∠b = 75° because ∠b and ∠f are corresponding angles
∠a = 105° because ∠a and ∠e are corresponding angles
∠d = 75° because ∠d and ∠h are corresponding angles
Step-by-step explanation:
The given diagram includes two parallel lines having a common transversal that crosses both (parallel) lines
By sing angle properties, we have;
∠e = 105° because ∠e and the 105° angle are vertically opposite angles formed by the same two straight lines and are therefore always equal
∠h = 180° - 105° = 75° because ∠h and the 105° angle are angles that form a straight line and are therefore supplementary angles which are angles that sum up to 180°. Therefore, ∠h + 105° = 180°, therefore ∠h = 75°
∠f = ∠h = 75° because ∠f and ∠h are vertically opposite angles
∠c = 105° because ∠c and the 105° are corresponding angles and corresponding angles are equal
Similarly, we have;
∠b = ∠f = 75° because ∠b and ∠f are corresponding angles
∠a = ∠e = 105° because ∠a and ∠e are corresponding angles
∠d = ∠h = 75° because ∠d and ∠h are corresponding angles

Expand (a-b)^7
Answer:
[tex]a^7-7a^6b+21a^5b^2-35a^4b^3+35a^3b^4-21a^2b^5+7ab^6-b^7[/tex]
Step-by-step explanation:
There are multiple ways of expanding a polynomial expression to a high degree. One way of doing it is to write out the problem in the multiplication form, multiply (a - b) by itself (7) times.
[tex](a-b)^7[/tex]
[tex]=(a-b)(a-b)(a-b)(a-b)(a-b)(a-b)(a-b)[/tex]
Now simplify, multiply two terms together,
[tex]=(a^2-2ab+b^2)(a^2-2ab+b^2)(a^2-2ab+b^2)(a-b)[/tex]
Repeat this process,
[tex]=(a^4-4a^3b+6a^2b^2-4ab^3+b^4)(a^3-3a^2b+3ab^2-b^3)[/tex]
Repeat this process one final time,

If out of a sample of 180 drivers prefer a standard transmission over automatic , about a standard transmission in a population of 900
A:700
B:22
C:360
D:200
Answer:
This is a matter of ratio and proportion, let us represent the unknown value as x. Since the two ratios are related,
40 : 180 :::: x : 900
40 / 180 = x / 900
x = (40/180)(900)
x = 200q

Which set of data has the highest interquartile range? Group of answer choices 8,12,14,14,20 8,12,14,14,22 9,13,14,15,19 all of the above
Given:
The given data set are:
8,12,14,14,20
8,12,14,14,22
9,13,14,15,19
All of the above
To find:
The set of data that has the highest interquartile range(IQR).
Solution:
We know that, the interquartile range(IQR) of a data set is the difference between the third quartile and first quartile.
[tex]IQR=Q_3-Q_1[/tex]
All the given data set has five values in ascending order. So, the first value is the minimum value, second value is the first quartile, third value is the median, the fourth value is the third quartile and the fifth value is the maximum value.
For 8,12,14,14,20,
[tex]IQR=14-12[/tex]
[tex]IQR=2[/tex]
For 8,12,14,14,22,
[tex]IQR=14-12[/tex]
[tex]IQR=2[/tex]
For 9,13,14,15,19,
[tex]IQR=15-13[/tex]
[tex]IQR=2[/tex]
All interquartile ranges are equal. So, all the data sets has t he highest interquartile range.
Therefore, the correct option is D.
