The three angles of a triangular sail have a sum of 180°. The largest angle measures 90° and the smallest angle measures x°. In degrees, which expression shows the measure of the third angle?
The measure of the third angle in the triangular sail, given that the largest angle is 90° and the smallest angle is x°, is found by subtracting the known angles from 180°, giving the expression 90° - x°.
Explanation:In a triangular sail, the sum of all the angles totals to 180°. Given that the largest angle measures 90° and the smallest angle measures x°. We find the measure of the third angle by using the fact that the sum of angles in a triangle equals 180 degrees. Therefore, if we subtract the two known angles from 180, we can locate the measure of the third angle. So the expression to determine the third angle in degrees would be 180° - 90° - x°, simplifying the expression to 90° - x°.

In an acute angled triangle ABC sin 2(A+B-C) = 1 and tan(B + C -A) =√3, then find the values of A, B and C
Given
In an acute angled triangle ABC .
sin 2(A+B-C) = 1
tan(B + C -A) =√3
To proof
As given in the question
In an acute angled triangle ABC .
first solving the equation
sin 2(A+B-C) = 1
[tex]2 ( A + B - C ) = sin^{-1} (1)[/tex]
As we know
1 = sin90°
put this in the above equation
we get
[tex]2 ( A + B - C ) = sin^{-1} (sin90^{\circ})[/tex]
2A + 2B - 2C = 90
A+B -C =45 ( first equation )
now solving the equation
we get
tan(B + C -A) =√3
[tex]B + C -A =tan^{-1} \sqrt{3}[/tex]
[tex]B + C -A =tan^{-1}(tan60^{\circ})[/tex]
B + C -A = 60 ( second equation )
As given acute angled triangle ABC
thus
∠A + ∠ B +∠ C = 180° ( Angle sum property of a triangle )
than the third equation becomes
A + B + C = 180 ( third equation)
Now solve the equation
A+B -C =45
and B + C -A = 60
Now subtract B + C -A = 60 from A+B -C =45
we get
(A+B -C) - (B + C -A) = 45-60
2A -2C = -15
Put this value in the equation 2A + 2B - 2C = 90
-15 + 2B = 90
2B = 90 + 15
B = 52.5
now subtracted -A +B +C = 60 from A + B + C =180
A + B + C +A - B - C =180 - 60
2A = 120
A = 60
Put the value of A , B in the equation A + B + C =180
60 + 52.5 + C = 180
C = 180 - 112.5
C = 67.5
Thus ΔABC is an acute angle triangle
therefore
∠A = 60°
∠B = 52.5°
∠C = 67.5°
Hence proved
An expression involves subtracting two numbers from a given first number under what circumstance will the value of the expression be negative
Final answer:
The value of an expression will be negative when the sum of the two numbers subtracted from a given first number is greater than the initial number itself, resulting in a negative outcome after applying the appropriate rules for addition and subtraction.
Explanation:
The value of an expression involving the subtraction of two numbers from a given first number will be negative under specific conditions. When the combination of the two numbers to be subtracted is larger than the first number, the result will be negative. To understand this, let's consider the basic rules of addition and subtraction with positive and negative numbers:
When two positive numbers add, the result has a positive (+ve) sign. For example, 3+2 = 5.When two negative numbers add, the result has a negative (−ve) sign. For example, -4 + (-2) = -6.When two numbers having opposite signs add, subtract the smaller number from the larger number, and the result has the sign of the larger number. For example, -5 + 3 = -2.In subtraction, we change the sign of the number being subtracted and then apply the rules of addition:
5 - (+3) = 5 - 3 = 2, where the sign of 3 is changed from positive to negative before adding.2 - (-6) = 2 + 6 = 8, where the sign of -6 is changed to positive before adding.Therefore, to have a negative result, the magnitude of the sum of the two numbers being subtracted should exceed the first number and, reflecting the sign rules, should result in a negative value. For instance, if the first number is 1 and the two numbers to subtract are 3 and 5, the expression would be 1 - (3 + 5) = 1 - 8 = -7, resulting in a negative value.
The sum of a number and twenty is greater than four times the number decreased by one solve the inequality
After translating the statement into an inequality and simplifying, we find that the solution to 'The sum of a number and twenty is greater than four times the number decreased by one' lies in the set of numbers that is less than 7.
Explanation:The question asks us to solve an inequality. Let's take the given statement: 'The sum of a number and twenty is greater than four times the number decreased by one'. We can translate that into an inequality as follows: x + 20 > 4x - 1, where x stands for the unknown number.
Now, let's simplify the inequality: we subtract x from both sides to get 20 > 3x - 1, and then add 1 to both sides, yielding 21 > 3x. Lastly, divide each side by 3 for the final inequality x < 7.
So the solution to the inequality means any number less than 7, when added to 20, is greater than four times the number minus one.

5ac+10ab-2c^2-4bc
Factor.
Final answer:
The expression 5ac+10ab-2c²-4bc is factored by first taking out the common factor of 2, and then grouping terms to extract 'a' from the first two and 'c' from the last two terms to get 2(a(5c + 5b) - c(c + 2b)).
Explanation:
To factor the expression 5ac+10ab-2c²-4bc, we look for common factors in each term. Observing the coefficients, we see that each term is divisible by 2. Also, we can factor out variable 'a' from the first two terms and variable 'c' from the last two terms. The factored expression is:
2a(5c + 5b) - 2c(c + 2b).
We can then extract the common factor 2 from both parts to get:
2(a(5c + 5b) - c(c + 2b)).
This is the fully factored form of the given expression.

A local club team is holding tryouts for six spots on the soccer team. Since there is not much time before a very important tournament they need to select the best players. Which method would be the best to ensure they select the "most talented" soccer players?
The method would be the best to ensure they select the "most talented" soccer players is They watch the players during tryouts and then put them on a list in order from the most skilled to the least skilled and then select the top six from the list.
The correct option is (A).
A. This method involves observing the players during tryouts and then ranking them from the most skilled to the least skilled. By selecting the top six players from this ranked list, the team is more likely to pick the most talented individuals based on their performance and skills demonstrated during the tryouts.
Option B (selecting the first six that show up) may not necessarily guarantee selecting the most talented players as eagerness to show up early does not always correlate with soccer skills.
Option C (selecting randomly from a hat) is not ideal because it does not take into account the players' actual skills and performance during tryouts. It relies solely on chance.
Option D (selecting the top three and bottom three) may overlook potentially talented players who fall in the middle range. Additionally, selecting the bottom three solely based on being the least skilled may not be fair or accurate.
Therefore, option A is the most suitable method for ensuring the selection of the "most talented" soccer players.
complete question given below:

Answer: d. w = -6Select the postulate of equality or inequality that is illustrated. If One Fourths (1/4) + One Fourths (1/4) = Two Fourths (2/4) and Two Fourths (2/4) = One Half (1/2), then One Fourth (1/4) + One Fourth (1/4) = One Half (1/2)
Answer:
'Transitive postulate of equality'
Step-by-step explanation:
To find : The postulate of equality or inequality that is illustrated.
Solution :
Given illustration is
[tex]\frac{1}{4}+\frac{1}{4}=\frac{2}{4}[/tex] and [tex]\frac{2}{4}=\frac{1}{2}[/tex]
Then, [tex]\frac{1}{4}+\frac{1}{4}=\frac{1}{2}[/tex]
Now, We let [tex]\frac{1}{4}+\frac{1}{4}=a,\frac{2}{4}=b,\frac{1}{2}=c[/tex]
According to this, [tex]a=b\text{ and }b=c\text{ then }a=c[/tex]
Which is 'Transitive postulate of equality'.
So, The required postulate of equality is transitive.
The equation 'One Fourth (1/4) + One Fourth (1/4) = One Half (1/2)' illustrates the Transitive Property of Equality. This mathematical property states that if 'a' equals 'b' and 'b' equals 'c', then 'a' must also equal 'c'. In this case, 'a' is '1/4 + 1/4', 'b' is '2/4', and 'c' is '1/2'.
Explanation:The mathematical postulate illustrated by the equation One Fourth (1/4) + One Fourth (1/4) = One Half (1/2) is the Transitive Property of Equality. In mathematics, the transitive property states that if a = b and b = c, then a = c. In this case, 'a' is One Fourth (1/4) + One Fourth (1/4), 'b' is Two Fourths (2/4), and 'c' is One Half (1/2). Because it has been established that 'a' equals 'b' (1/4 + 1/4 = 2/4) and 'b' equals 'c' (2/4 = 1/2), the Transitive Property of Equality allows us to conclude that 'a' equals 'c' (1/4 + 1/4 = 1/2).

The ratio of the number of chickens to the number of ducks on a farm was 3 : 8. There were 40 more ducks than chickens. When half the chickens and some of the ducks were sold, the ratio of the number of chickens to the number of ducks became 3 : 4. How many ducks were sold?
Answer:
The number of ducks were sold be 48
Step-by-step explanation:
Let the number of chicken be 3x and the number of ducks on a farm be 8x.
From the given conditions, it is states that there were 40 more ducks than chicken, i.e
8x+40=3x
or [tex]8x-3x=40[/tex]
or 5x=40
Simplify:
[tex]x=8[/tex]
Then, the number of chicken be [tex]3x=3\cdot 8=24[/tex]
and the number of ducks be, [tex]8x=8\cdot 8=64[/tex].
Since it is given that half the chicken and some of the ducks were sold ; then the ratio of the number of chicken to the number of ducks became 3:4
Let the number of ducks that were sold be y.
now by above condition, we have
[tex]\frac{12}{64-y}= \frac{3}{4}[/tex]
then,
[tex]12\cdot 4= 3\cdot (64-y)[/tex]
Simplify:
[tex]48=192-3y[/tex] or
[tex]3y=192-48[/tex] or
[tex]3y=144[/tex]
On simplify we get,
y=48.
Therefore, the number of ducks were sold be, 48.
Final answer:
By setting up simultaneous equations based on the given ratios and the additional information, we can determine that initially there were 120 chickens and 160 ducks. After selling half the chickens and some ducks, 80 ducks were sold to maintain the new ratio of 3:4.
Explanation:
Let's denote the number of chickens as c and the number of ducks as d. According to the problem, the initial ratio of chickens to ducks is 3:8, so we can write the relation as 3d = 8c. Since there are 40 more ducks than chickens, we have the equation d = c + 40.
Now we'll solve these two equations simultaneously. Multiplying both sides of the first equation by c to eliminate fractions, we get 3d = 8c, or 3(c + 40) = 8c. Simplifying this, we find that c = 120 (the number of chickens) and d = 160 (the number of ducks).
After selling half of the chickens and some ducks, the ratio becomes 3:4. The new number of chickens is 120/2 = 60. Let's call the new number of ducks d'. Then, we have 3d' = 4x60. Solving for d', we get d' = 80. Since initially there were 160 ducks and now there are 80, 80 ducks were sold.
