The value of x in the triangle is 20
How to determine the value of x?From the triangle, we have the following equivalent ratios:
5x+ 10 : 121 = 10 : 11
Express as fraction
5x + 10/121 = 10/11
Multiply both sides by 121
5x + 10 = 110
Subtract 10 from both sides
5x = 100
Divide both sides by 5
x = 20
Hence, the value of x in the triangle is 20

Two players, A and B, are playing an asymmetrical game. There are n points on the game board. Each turn player A targets a pair of points and player B says whether those two points are connected or unconnected. A can target each pair only once and the game ends when all pairs have been targeted. Player B wins iff a point is connected with all other points on the very last turn, while player A wins if any point is connected with all other points on any turn but the very last one OR if no point is connected to all other points after the last turn. For what values of n does either player have a winning strategy?
Answers
The values of n that either player has a winning strategy is when the number of points are odd such as 3:-
How to depict the strategy?The game is begun by A and then its chance of B to play the game alternatively, then all the possible moves are 1,2; 2,3; 1,3 in which all possible pairs are selected.
If the game end on an even number of moves then the game is won by A. For B to win, these points should be connected at the very end of the game.
Similarly, for even number of moves B wins the game when number of points is odd.
If the number of points is even the opposite of this happens that is, for even moves B wins and for odd number of moves A wins.

The given line segment has a midpoint at (3, 1).
On a coordinate plane, a line goes through (2, 4), (3, 1), and (4, negative 2).
What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?
Answers
An equation is formed of two equal expressions. The equation of the perpendicular bisector is y=(1/3)x.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation of the line that passes through (2, 4), (3, 1), and (4,-2), are,
m = (4-1)/(2-3) = 3/-1 = -3
Since the product of the slope of two perpendicular lines is -1. The slope of the perpendicular line is,
m₁m₂ = -1
(-3) m₂ = -1
m₂ = 1/3
Since the line is the perpendicular bisector it will pass through midpoint,
1 = (1/3)(3) + C
1 = 1 + C
C = 0
Hence, the equation of the perpendicular bisector is y=(1/3)x.

How to convert the polar coordinate to a cartesian coordinate?The polar coordinate system in geometry is a two-dimensional latitude and longitude that uses the distance from a reference point and the angle from an optical axis are used to identify each point's location on a plane. This polar axis is the ray emanating from the pole in the direction of the point of comparison, which is referred to as the pole.
The cartesian coordinate is (x, y) and polar coordinate is (r, θ). Then the relation is given as,
x = r cos θ
y = r sin θ
The angle is 330° and the radius is one. Then we have
x = 1 x cos 330°
x = (√3) / 2
y = 1 x sin 330°
y = - 1/2
The coordinates of the point on the unit circle will be ((√3) / 2, - 1/2).

What is 1.7⎯⎯ expressed as a fraction in simplest form?

Step-by-step explanation:
Step 1: Write down the number as a fraction of one:
1.7 = 1.7/1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,
1.7/1
= (1.7 × 10)/ (1 × 10)
= 17/10
(This fraction is alread reduced, We can't reduce it any further).
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 17/

Answers
Answer:
Step-by-step explanation:
We'll look for an equation with the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0.
A line parallel to y=3x+6 will have the same slope, 3.
We can write y=3x+b. Any value of b can be used to generate a parallel line.
If we want that line to go through a specific point, such as (0,-2), we need to find a value of b that shifts the line so that it includes (0,-2). This can be done by using that point in the equation y=3x+b:
y=3x+b
-2=3*(0)+b for point (0,-2)
b = -2
The equation becomes y=3x-2
See the attached plot.

If sin Q = 4/5, cos P + cos Q
Answers
The value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We know that:
P + Q are complementary, which means that
P+Q = 90°
Then R is a right angle, i.e. it measures 90°.
sin(90-x) = cos (x)
cos(90-x) = sin (x)
Then sinQ = 4/5
cos(90-Q) = cosP = 4/5
Now sin²(P) + cos²(P) = 1
sin²(P) = 1 - cos²(P)
sin²(P) = 1 -[4/5]² =9/25
sin(P) = 3/5
cos(Q) = sin(P) = 3/5
cos(P) + cos(Q) = 4/5 + 3/5 = 7/5
Thus, the value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.

[tex]\boxed{\mathrm{No}}[/tex] ⇒ It doesn't pass the Vertical line test. The line touches the graph more than once.

Since the line touches the graph only once, this graph is a function, and Option A. is not right; we can cross it out.

Is the graph a one-to-one function?[tex]\boxed{\mathrm{Yes}}[/tex] ⇒ It passes the horizontal line test; it touches the graph only once.
[tex]\boxed{\mathrm{No}}[/tex] ⇒ It doesn't pass the test; the line touches the graph

Since a horizontal line touches the graph more than once, this function is not one-to-one.
Option B. isn't right either.
Two down, two to go! ^^
However, look what Option C. is. The graph we're given is indeed a function, and it's not one-to-one.
So I choose Option C.
Let's ensure our answer is correct by checking the last option:
Is the graph a linear function?[tex]\boxed{\mathrm{Yes}}[/tex] ⇒ Its graph is a straight line.
[tex]\boxed{\mathrm{No}}[/tex] ⇒ Its graph isn't a straight line.

As we can see, the given graph is not a staight line; thus, Option D. is also wrong.
Thus, Option C. is the correct answer.
