original angle = 34°complement angle = 56°supplement angle = 146°What are defined as the complement and supplement angle?If a sum of two angles is 180 degrees, they are referred to as supplementary angles because they form a linear angle when combined. If a sum of two angles is 90 degrees, they are termed to be complementary angles because they form a right angle when combined.Now, for the given question.
Let the given angle be 'x'.
Then, the complement of the angle will be: 90 - x.
6 times the complement = 6(90 - x)
6 times the complement is 44 less; 6(90 - x) - 44.
Now, the supplement of the angle is; 180 - x.
Two time the supplement = 2(180 - x)
The equation will form as;
2(180 - x) = 6(90 - x) - 44
360 - 2x = 540 - 360 - 44
Simplifying the equation;
x = 34.
Thus, the original angle is 34°.
complement angle = 90 - x
= 90 - 34
= 56°
Thus, complement angle = 56°
supplement angle = 180 - x
= 180 - 34
= 146
supplement angle = 146°
Thus, the values of the angles are obtained.

in triangle abc, angle b is 120∘ . it contains bisectors aa1, bb1 and cc1. prove that the angle a1b1c1 is 90∘
The triangle formed by the feet of angle bisectors of a triangle with a single angle measure of 120° is the Right Triangle.
What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental shape in geometry. Triangle ABC denotes a triangle with vertices A, B, and C. In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane.So,
In triangle ABC, ∠A = 120°.
Let AD, BE, and CF be the respective angle bisectors of A, B, and C.AC in ABD is the exterior angles bisector (as DAC=CAX=60°).BE is the internal angle bisector that meets at E. E is the ex-center of ABCD.As a result, DE is the exterior angle bisector of ABCD.
Then, ADE=EDC, and ADC=2ADE.Similarly, for the ABC, F is ex-center because AB is the exterior angle bisector and CF is the interior angle bisector.
As a result, DF is the exterior angle bisector.
∠ADF = ∠FDB, ∠BDA = 2∠ADFBC is a straight line.
∠BDA+∠ADC=180°2∠ADF+2∠ADE=180°∠ADF+∠ADE=90°So, DEF is the right triangle.
As a result, the triangle formed by the feet of angle bisectors of a triangle with a single angle measure of 120° is the Right Triangle.

First of all, every number in each row is odd, so we can eliminate 392 and 394.
The number of elements in each row forms an arithmetic sequence:
• 1st row : 1 element
• 2nd row : 3 elements - and 3 - 1 = 2
• 3rd row : 5 elements - and 5 - 3 = 2
• 4th row : 7 elements - and 7 - 5 = 2
and so on, so that the [tex]n[/tex]-th row has [tex]1 + 2(n-1) = 2n - 1[/tex] elements.
This means that in [tex]n-1[/tex] complete rows, there is a total of
[tex]\displaystyle \sum_{i=1}^{n-1} (2i-1) = n^2 - 2n + 1[/tex]
elements, so that the first element in the subsequent [tex]n[/tex]-th row is the [tex](n^2-2n+2)[/tex]-th number in the sequence {1, 3, 5, 7, …}, i.e the [tex](n^2-2n+2)[/tex]-th odd positive integer. To compute the sum, I use the following well-known formulas.
[tex]\displaystyle \sum_{i=1}^n 1 = n[/tex]
[tex]\displaystyle \sum_{i=1}^n i = \frac{n(n+1)}2[/tex]
Now, the [tex]n[/tex]-th term of the sequence {1, 3, 5, 7, …} is simply [tex]2n-1[/tex], the [tex]n[/tex]-th odd positive integer. So the first element in the [tex]n[/tex]-th row is
[tex]2(n^2-2n+2) - 1 = 2n^2 - 4n + 3[/tex]
and hence the 1st element of the 15th row is
[tex]2\cdot15^2 - 4\cdot15 + 3 = \boxed{393}[/tex]

with show work needed. a and b.
a)
Solution,
Given,
Cost for 1 pen = $ 1.50
= 1.50×100 cents
= 150 cents
Cost for 1 ruler = 80 cents
No. of Pens needed to be bought = x
No. of rulers needed to be bought = x+10
Now,
Cost for x pens = x×150 cents
= 150x cents
Cost for (x+10) rulers = (x+10)×80 cents
= 80x cents+800 cents
Then,
Total cost = 150x cents+(80x cents+800 cents)
= 150x cents+80x cents+800 cents
= 230x cents+800 cents
= $(230x ÷ 100)+$(800 ÷ 100)
= $2.3x + $8

Choose the associated property
The Associative property is not displayed by any of the given equations.
The associative property of several binary operations in mathematics states that the outcome will not change if the parenthesis in an expression are rearranged.
The order in which the operations are carried out within an expression that has two or more instances of the same associative operator in a row doesn't matter as long as the order of the operands is left untouched.
Examples of associative property :
[tex]{\displaystyle {\begin{aligned}(7+8)+1&=7+(8+1)=9\,\\5\times (3\times 7)&=(5\times 3)\times 7=24.\end{aligned}}}[/tex]
The parentheses were rearranged on each line, but the expression values were left alone. It can be argued that "addition and multiplication of real numbers are associative operations" because this is true for addition and multiplication of all real numbers.
Here 8=8+0 displays additive identity property.
10×1=10 displays multiplicative identity
5+0=5 displays displays additive identity property.

The dimensions of the playing field the width is 54 yards and the length is 210 yards.
Given that the perimeter of the rectangular playing field is 528 yards and the length of the field is 6 yards less than quadruple the width.
Let the width of the rectangular playing field is x yards and it is given that the length of the field is 6 yards less than quadruple the width means the length is 4x-6.
As we know that the perimeter of the rectangle is two times the sum of length and breadth so.
P=2(l+w)
As it is given that the perimeter is 528 yards.
So, we will substitute all the values in the formula, we get
528=2(4x-6+x)
528=2(5x-6)
528=10x-12
528+12=10x-12+12
540=10x

Harry drove for 3 hours on the freeway, then decreased his speed by 20 miles per hour and drove for 6 more hours on a country road. If his total trip was 483 miles, then what was his speed on the freeway?
Harry's speed on the freeway is 67 miles per hour
Time Harry drove on freeway = 3 hours
Time Harry drove on country road = 6 hours
Total distance covered by him = 483 miles
Let his speed be x miles per hour
Formula to be used:
Speed*Time = Distance
Therefore, the distance covered by him on the freeway = 3x -----(1)
Distance covered by him on country road = 6(x - 20)------(2)
Formulating the equations using (1) and (2)
3x + 6(x-20) = 483
3x + 6x - 120 = 483
9x = 603
x = 67 miles per hour
So, his speed on the freeway is 67 miles per hour and on the country road it is 47 miles per hour
