Which angle refers to the same angle as \angle BPF∠BPFangle, B, P, F?
We have: ∠APC + ∠BPC = 180⁰ (adjacent corner)
=> ∠APC + 133⁰ = 180⁰
=> ∠APC = 180⁰ - 133⁰ = 47⁰
Beside: x = ∠BPD = ∠APC = 47⁰ (opposite corner)
ANSWER: x = 47⁰
Ok done. Thank to me :3
The value of the angle x will be equal to 47⁰.
What is an angle?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
It is given that ∠APC + ∠BPC = 180⁰ (adjacent corner)
The angle x will be calculated as below:-
=> ∠APC + 133⁰ = 180⁰
=> ∠APC = 180⁰ - 133⁰ = 47⁰
Beside: x = ∠BPD = ∠APC = 47⁰ (opposite corner)
Therefore, the value of the angle x will be equal to 47⁰.

What is the range of possible sizes for side x?
Answer: 0.5 < x < 16.5.
Step-by-step explanation: Two sides of triangle: 8.0 units and 8.5 units
Measure of third side = x
According to the triangle's inequality,
Sum of any two sides > third side. (i)
Difference between the sides < third side. (ii)
If x is the third side, then
x < 8+8.5 [Using (i)]
i.e. x< 16.5
Also, x > 8.5-8 [Using (ii)]
i.e. x> 0.5
Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.
The range of possible sizes for side x is,
⇒ 0.5 < x < 16.5
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Two sides of the triangle are 8.5 and 8.
Now, The range of possible sizes for side x is,
⇒ x < 8.5 + 8
⇒ x < 16.5
⇒ x > 8.5 - 8
⇒ x > 0.5
Thus, The range of possible sizes for side x is,
⇒ 0.5 < x < 16.5

Answer: Alligators
Step-by-step explanation: This entire paper is just about combining like terms.
I won't go too in depth about it since it's self-explanatory, but I'll explain it just a bit. Like terms are two terms that have the same variable. For example, 19 and 24 are like terms since they are both numbers. 15x and 18x are like terms since they are both the same variables. 2y and 5y are like terms since they are both the same variables. However, 3x and 4y are NOT like terms, they do not have the same variable.
Also, variables that have different exponential powers are also not like terms. For example, 5x^2 and 7x are not like terms as one is squares and one is to the 1st power. Similarly, 3x^3 is not the same variable as 2x^4.
When you have 5x and -2x, you subtract 5x and 2x. Thus, the combination would be 3x. When you have -4x - 2x, you would get -6x, and if you have -4x + 2x, you would get -2x.
What you were supposed to do is simplify the equations by combining like terms, and then crossing off the letters that correspond to what you have left in the expression. The remaining letters should spell out a joke.

So far this year, Adam has played 30 games of chess and has only won 6 of them. What is the minimum number of additional games he must play, given that he is sure to lose at least one-third of them, so that for the year he will have won more games than he lost?
A) 24
B) 57
C) 87
D) It is not possible for Adam to do this.
The correct answer is B) 57, but not sure how?
Answer:
Step-by-step explanation:Yikes. Just so we’re all clear—this is not a real SAT question.
So far, Adam’s record is 6 wins/30 games. If he plays x more games, his record will be:
image
You find the minimum x such that the fraction is greater than ½, which would mean he won more than ½ of his games.
Let’s do some math!
image
So if he plays 54 more games, and wins 2/3 of them, he’ll have the same number of wins as losses. Check on that to make sure: He’ll have played 30 + 54 = 84 games, and won 6 + (2/3)54 = 42 of them. Yep, that works.
Now here is where it gets tricky (and why this question is not SAT-caliber). Remember that he’s losing 1/3 of his games. If his 52nd, 53rd, and 54th additional games were win, win, loss, then he would have had, very briefly, a winning record after his 53rd additional game.
His 55th additional game is another chance at a winning record. If he loses that game, then he’ll win the next two, and have a winning record for sure by the 57th additional game. From there, if he continues winning 2/3 of his games, he’ll have a winning record forever.

How will removing this rent affect the mean and median?
The way that this action is going to affect the mean and the mean and the median value would be decreased than what it was supposed to be.
What is the mean?In a frequency distribution, the mean is the number that is used to represent the average of a group of data. To get the mean, you have to add up the numbers in the data set and divide by the total number in the data set.
The formula is fx/n
When the average of $4800 is removed from the data set, the mean is going to decrease by the number and the value of fx would also decrease. Hence we can conclude that it would cause the value to reduce.
The median is the middle value, it would also cause the median in the data set to be smaller than it was.

Figure B is a scaled copy of Figure A.
What is the scale factor from Figure A to Figure B?
Answer: x = 60°
Step-by-step explanation:
We know a circle is equal to 360°, so we can subtract from 360° to find x using vertical angles and other given details.
Vertical (opposite) angles are equal to each other. This is why, for example, we know AGE and FGC are both 30°.
See attached for a breakdown of the angles.
360° - 30° - 30° - 90° - 90° = 2x
120° = 2x
60° = x
Answer:
x = 60°
Step-by-step explanation:
Hello!
The sum of angles on a line is 180°.
Given that Angle G is 90°, the other measure on Line DB would also be 90°. The missing angle next to x can be called y.
x° + y° = 90°Angle YThe Angle y can be calculated by using the Vertical Angles Theorem. The theorem states that if two non-adjacent angles are formed by the intersection of two lines, the measures of the angles are congruent.
This means that the measure of Angle y is 30°, as the 30° angle and y are non-adjacent and are formed by the intersection of lines AC and EF.
Angle XWe can now solve for x by plugging in 30° for y in the equation.
x° + y° = 90°x° + 30° = 90°x° = 60°The value of x is 60°.

the sum of the length of a side of two squares is 18cm and the sum of their areas is 212 cm^2. find the length of a side of the smaller square
Step-by-step explanation:
lengtha + b = 18cm
a = 18 - b
Areaa² + b² = 212cm²
(18-b)² + b² = 212
324 - 36b + b² + b² = 212
2b² - 36b + 112 = 0
b² - 18b + 56 = 0
b² - 4b - 14b + 56 = 0
b(b-4) -14(b - 4) = 0
(b-4) (b-14) = 0
b-4 = 0 OR. b-14 = 0
b = 4 cm b = 14 cm
so 4cm < 14cm
so , length of a side of the smaller square is 4cm .......
And , large square's = 14cm .....
Answer:
square one sides = 14, 14

Is Figure BBB a scale copy of Figure AAA?
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
Here, we have to determine if Figure B is a scale copy of Figure A, we need to compare the corresponding sides of the two triangles and check if the ratios of their side lengths are equal.
Figure A has side lengths: 3.6, 2, and 5.
Figure B has side lengths: 8.9, 4, and 11.3.
Let's check if the ratios of corresponding side lengths are equal:
Ratio of corresponding side lengths of A and B:
3.6 / 8.9 ≈ 0.4045
2 / 4 = 0.5
5 / 11.3 ≈ 0.4425
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
In order for two triangles to be scale copies of each other, all corresponding side lengths must have the same ratio.
Since the ratios of side lengths in Figure A and Figure B are not equal, they are not scale copies of each other.

The total of the ratio = the total number of students
2 + 3 = 5
5 parts = 200 students
1 part = 200 / 5 = 40 students
b) Therefore, the students who liked Nepali(2 parts) = 2 × 40 = 80
c) The students who liked Social Studies(3 parts) = 3 × 40 = 120
Since, 45 students liked both subjects, then those who liked Social Studies only:

Answer: 29 centimeters long
Step-by-step explanation: What you want to do in this kind of situation is to combine all like terms. After, you would get 6x + 24 = 150. What you would do here is to get 6x by itself by subtracting 24 on both sides. Now 6x = 126, to isolate the variable you divide 6 on both sides to get x = 21. However, the questions is asking for the longest side and you know that x + 8 will be the greatest out of all. So, x = 21 + 8 equals 29 centimeters. I hope this helps, please give me a brainlest! :)
