to work it out:
180-110= 70
because there are two unknown angle we're gonna assume they're both the same amount. So if they are both the same and equal then we need to half 70 which will be equal to the two sided. So. 70/2= 35
So the 2 x's = 35 each

you need to put this all into an equation so:

A circle is centered at C(0,0)C(0,0)C, left parenthesis, 0, comma, 0, right parenthesis. The point M(0,\sqrt{38})M(0,38 )M, left parenthesis, 0, comma, square root of, 38, end square root, right parenthesis is on the circle.
Where does the point N(-5,-3)N(−5,−3)N, left parenthesis, minus, 5, comma, minus, 3, right parenthesis lie?
Answers
Answer:
Inside the circle, a distance of [tex]\sqrt{34}[/tex] from the center of the circle.
Step-by-step explanation:
Center of circle is at (0,0)
One point of the circle is at (0,[tex]\sqrt{38}[/tex])
Since the only known point is in the y-axis, the radius of the circle must be [tex]\sqrt{38}[/tex].
[tex]\sqrt{38}[/tex] = 6.164
So the point (-5,-3) is still inside the circle as the distance from point (-5,-3) to the center of the circle is [tex]\sqrt{(5)^2+(-3)^2}[/tex] or [tex]\sqrt{34}[/tex] which is less than the radius of the circle.
Point N(-5, -3) lies inside the circle.
We have,
To determine the location of point N(-5, -3) in relation to the given circle centered at C(0, 0), we can calculate the distance between point C and point N.
- If the distance is equal to the radius of the circle, then N lies on the circle.
- If the distance is greater than the radius, N lies outside the circle.
- If it is smaller, N lies inside the circle.
Let's calculate the distance between C(0, 0) and N(-5, -3):
Distance = √[(x2 - x1)² + (y2 - y1)²]
= √[(-5 - 0)² + (-3 - 0)²]
= √[25 + 9]
= √34
Since the distance (√34) is less than the radius of the circle, which is √38 (distance between C and M), we can conclude that the point N(-5, -3) lies inside the circle centered at C(0, 0).
Thus,
Point N(-5, -3) lies inside the circle.

Given that a circle is centered at C(0, 0) and passes through the point M(0, √38), determine the location of the point N(-5, -3) in relation to the circle. Does point N lie inside, outside, or on the circle?
What's the number that is halfway between numbers 0 and 121?
Answers
Halfway Between 0 and 121
Halfway Between
When you ask "What number is halfway between 0 and 121?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=0 and Y=121.
Halfway Between Line
To find the number halfway between 0 and 121, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 0 and 121 into our formula, we get:
(0 + 121)/2 = 60.5
Thus, the number halfway between 0 and 121 is 60.5
Answer:
solution given;
half way between 0 and 121=?
let a=0
and
b=121
we have
halfway =[a+b]/2=[0+121]/2=60.5
half way between 0 and 121 is 60.5

Answers
Answer:
x = 0, y = 2
Step-by-step explanation:
Substitute the first equation into the second equation so 3x + 3(x+2) = 6. Simplify this to get x = 0. Plug x = 0 back into the first equation to get y = 2.
Answer:
x = 0, y = 2
Step-by-step explanation:
y = x + 2
3x + 3y = 6
3x + 3(x + 2) =6
3x + 3x +6 = 6
6x = 0
x = 0
y = x + 2 = 0 + 2 = 2

Determine whether the sequence is arithmetic. If it is, determine the common difference.
--12, 10, 32, 54,...
Answers
Answer:
The sequence is arithmetic
Step-by-step explanation:
Here we want to determine the sequence is arithmetic
If the sequence was arithmetic, the difference between the terms would be constant
We have this as;
10-(-12) = 22
32-10 = 22
54-32 = 22
As we can see, the difference is constant and so we have it that the sequence is arithmetic

Graph the equations
Y=400+50x
Y=300+25x
1.) from the graph at what time will the they have the same height
I’ll give u brainlist pls help
Answers
Answer:
We conclude that, at 4 minutes, both will have the same height which is 200 feet.
Step-by-step explanation:
Given the system of equations
[tex]y=400+50x[/tex]
[tex]y=300+25x[/tex]
Important Tip:
The point of intersection of the two lines would give us the point at which both have the same height.Graphing the system of equations
The graph of the equation y = 400 + 50x
First, determine the y-intercept of the equation y = 400 + 50x by substituting x = 0
[tex]y = 400 + 50x[/tex]
[tex]y = 400 + 50(0)[/tex]
[tex]y = 400 + 0[/tex]
[tex]y = 400[/tex]
Thus, we determine that the ordered pair (0, 400) represents the y-intercept of the equation y = 400 + 50x.
Next, determine the x-intercept of the graph of the equation y = 400 + 50x by substituting y = 0
[tex]y = 400 + 50x[/tex]
[tex]0=400+50x[/tex]
switch sides
[tex]400+50x=0[/tex]
Subtract 400 from both sides
[tex]400+50x-400=0-400[/tex]
Simplify
[tex]50x=-400[/tex]
Divide both sides by 50
[tex]\frac{50x}{50}=\frac{-400}{50}[/tex]
Simplify
[tex]x=-8[/tex]
Thus, we determine that the ordered pair (-8, 0) represents the x-intercept of the equation y = 400 + 50x.
Important Tip:
The point at which the graph crosses the y-axis is called the y-intercept. The point at which the graph crosses the x-axis is called the x-intercept.The red graph on the diagram represents the equation y = 400 + 50x having the y-intercept (0, 400) and x-intercept (-8, 0)
Please check the attached diagram.
The graph of the equation y = 300 + 25x
Now, determine the y-intercept of the equation y = 300 + 25x by substituting x = 0
[tex]y = 300 + 25x[/tex]
[tex]y = 300 + 25(0)[/tex]
[tex]y = 300 + 0[/tex]
[tex]y = 300[/tex]
Thus, we determine that the ordered pair (0, 300) represents the y-intercept of the equation y = 300 + 25x.
Next, determine the x-intercept of the graph of the equation y = 300 + 25x by substituting y = 0
[tex]y=300+25x[/tex]
[tex]0 = 300 + 25x[/tex]
switch sides
[tex]300+25x=0[/tex]
Subtract 300 from both sides
[tex]300+25x-300=0-300[/tex]
Simplify
[tex]25x=-300[/tex]
Divide both sides by 25
[tex]\frac{25x}{25}=\frac{-300}{25}[/tex]
Simplify
[tex]x=-12[/tex]
Thus, we determine that the ordered pair (-12, 0) represents the x-intercept of the equation y = 300 + 25x.
The blue graph on the diagram represents the equation y = 300 + 25x having the y-intercept (0, 300) and x-intercept (-12, 0)
Please check the attached diagram.
Analyze the POINT OF INTERSECTION:
As we already know that the point of intersection of the two lines would give us the point at which both have the same height.
The diagram indicates that:
at x = -4, the value of y = 200.
It is the point where both lines meet.
Thus, the point of intersection of the two lines is:
(x, y) = (-4, 200)
Conclusion:
As x represents the time in minutes and y represents the height in feet.
Thus, we conclude that at x = 4 minutes, both will have the same height i.e. y = 200 feet
Therefore, we conclude that, at 4 minutes, both will have the same height which is 200 feet.

The ratio of the perimeter of a square A and square B is 4:3. The side of square B is 3 m less than the side
of square A. What is the length of the side of square A?
please answer
Answers
Answer:
x = 12
Step-by-step explanation:
x = length of side of square A
'x-3' represents length of side of square B
Perimeter of square A = 4x
Perimeter of square A = 4x - 12
we can set up the following proportion based on ratio of 4:3
4x / 4 = 4x - 12 / 3
cross-multiply:
4(3x) = 4(4x-12)
12x = 16x - 48
-4x = -48
x = 12
