Answer:
Step-by-step explanation:
55 +80 + ∠C = 180 {Angle sum property}
135 + ∠C = 180
∠C = 180 - 135
∠C = 45
The side opposite to the biggest angle is the longest side
Biggest angle is ∠B. So the longest side is AC
Smallest angle is ∠C. So, the shortest side is BA

The circle below is centered at the origin and has a radius of 2. What is its equation?
What is the quotient of the synthetic division problem below, written in polynomial form?
-1| 1 7 15 9 7
Answer:
Step-by-step explanation:
If we have 5 terms to the right of the -1 outside the box thing, that means that our original polynomial is a 4th degree (the degree is one lower than the number of terms in order to allow for the constant which has no variable). Set up the synthetic division as shown in the problem. The rule is to bring down the first term, the 1 to the right of the box, multiply it by the number outside, -1, and put that product up under the next number in line inside the box. Like this:
-1 | 1 7 15 9 7
-1
1
Now add straight down, multiply the sum by -1 and put that product up under the next term in line, the 15:
-1 | 1 7 15 9 7
-1 -6
1 6
Then add straight down again, multiply the sum by -1 and put that product up under the next term in line, the 9:
-1 | 1 7 15 9 7
-1 -6 -9
1 6 9
Then do the same thing. Add straight down, multiply the sum by -1 and put the product up under the next term in line, the 7:
-1 | 1 7 15 9 7
-1 -6 -9 0
1 6 9 0 7
This is the final result. The last number, the 7 is the remainder, but the rest of it makes up what we call the depressed polynomial and is a polynomial that is one degree less than the degree we started with. So this depressed polynomial is a 3rd degree. The numbers are the coefficients on the x terms:
[tex]1x^3+6x^2+9x+0R7[/tex] or more simply stated:
[tex]x^3+6x^2+9xR7[/tex]

What should be subtracted from thrice the rational number -8/3 to get
5/2?
Answer: -21/2 or -10.5
Step-by-step explanation:
Let x be the number that is going to be subtracted from the rational number
3 × (-8/3) - x = 5/2 ⇒ Write the equation
-8 - x = 5/2 ⇒ Do multiplication
-8 - x + x = 5/2 +x ⇒ Add x on both sides
-8 = 5/2 + x ⇒ Simplify
-8 - 5/2 = 5/2 + x - 5/2 ⇒ Subtract 5/2 on both sides
x = -21/2 = -10.5 ⇒ Simplify
Hope this helps!! :)

Two tapes, red and green, with lengths of 415 feet and 780 feet respectively are to be cut into pieces of equal length without remainder. Find the greatest possible length of the pieces.
Answer: _ feet
Answer:
The greatest possible length of the pieces is 5 feet
Step-by-step explanation:
Red = 415 feet
Green = 780 feet
Find the greatest possible length of the pieces.
Find the Highest common factor
415 = 1, 5, 83, 415
780 = 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390 and 780
The Highest common factor of 415 and 780 is 5
The greatest possible length of the pieces is 5 feet
Red = 415/5
= 83 pieces
Green = 780/5
= 156 pieces

The bisection of ZD
O The bisection of CD.
An angle congruent to ZD
O A line segment congruent to AB
Answer:
Solution given:
the use of compass seems that it divides the angle D in half so
o the bisection of <D.The correct answer is A. The bisection of angle D. In the given figure, the construction is shown to bisect angle D. This means that the angle bisector divides angle D into two equal angles.
The construction of the bisector of an angle involves dividing the angle into two congruent halves. This can be done using the following steps:
Place the compass on the vertex of the angle and draw an arc that intersects both sides of the angle.
Without changing the compass width, place the compass on each of the two points where the arc intersects the sides of the angle, and draw two arcs that intersect each other.
Draw a straight line connecting the vertex of the angle to the point where the two arcs intersect. This line is called the angle bisector.
The angle bisector divides the angle into two congruent angles, with each half measuring half of the original angle.
In the given figure, the construction is shown to bisect angle D. This means that the angle bisector divides angle D into two equal angles. Therefore, the correct answer is A. The bisection of angle D.

f(x) = 3x + 2
What is f(5)?
Answer:
17
Step-by-step explanation:
F(5) means you replace/ substitute all x's with 5's
Therefore, it would look like this:
f(x) = 3x + 2
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17
Samuel played a video game. He gained some points, lost 87 points, and
finished with less than 320 points, Which of the following inequality
represents the given situation?
A.) n-87 < 320
B.) N + 87 < 320
C.) N-87 = 320
D.) n +87= 320
Answer:
A
Step-by-step explanation:
The correct inequality that represents the given situation is: A.) n - 87 < 320.
How to explain the equationThe situation states that Samuel played a video game and gained some points. Let's represent the points he gained as 'n'.
Next, it is mentioned that he lost 87 points. To represent this in the inequality, we subtract 87 from the initial points gained, which gives us 'n - 87'.
Finally, the situation specifies that Samuel finished with less than 320 points. This means that the final score, represented by 'n - 87', is less than 320.
This inequality represents that the initial points gained by Samuel (n) minus 87 points is less than 320 points, indicating that his final score is less than 320 points after losing 87 points.

Which statements are true about the rectangular pyramid below? Select three options.
Answer:
Options (1), (2) and (4)
Step-by-step explanation:
1). Since, pyramid given in the picture is a rectangular pyramid,
Area of the rectangular base = Length × Width
= 6 × 4
= 24 cm²
2). There are four lateral sides of the pyramid.
3). Lateral sides of the pyramid are not congruent.
4). Total surface area = Area of the lateral sides + Area of the rectangular base.
Area of one lateral side = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(4.6)(4)[/tex]
= 9.2 cm²
Area of second lateral side = [tex]\frac{1}{2}(6)(4)[/tex]
= 12 cm²
Area of the lateral sides = 2(9.2) + 2(12)
= 42.4 cm²
Total surface area = 42.4 + 24
= 66.4 cm²
5). Area of the one face = [tex]\frac{1}{2}(6)(4)[/tex]
= 12 cm²
Area of the second face = [tex]\frac{1}{2}(4.6)(4)[/tex]
= 9.2 cm²
Therefore, Options (1), (2) and (4) are the correct options.

A mouse has made holes in opposite corners of a rectangular kitchen. The width of the kitchen is 2 meters and the distance between the mouse's holes is 3 meters. What is the length of the kitchen? If necessary, round to the nearest tenth.
Answer:
The length of the kitchen is 2.23 meters.
Step-by-step explanation:
Given that a mouse has made holes in opposite corners of a rectangular kitchen, and the width of the kitchen is 2 meters and the distance between the mouse's holes is 3 meters, the following calculation must be performed to determine what is the length of the kitchen, using the Pythagorean theorem:
Width = 2 meters
Hypotenuse = 3 meters
2 ^ 2 + X ^ 2 = 3 ^ 3
4 + X ^ 2 = 9
X ^ 2 = 9 - 4
X = √ 5
X = 2.236
Therefore, the length of the kitchen is 2.23 meters.
