Step-by-step explanation:
A. DEG =x+20 (alt angles DellFg)
B. DHG =110 (opp angles of cyclic quad)
X+20+2x+10=180(remember to solve for x)
I NEED HELP WITH THIS one angle of a triangle measured 145 degrees. The other two angles are in a ratio of 2:3. what are the measures of those two angles?
Answer:
Step-by-step explanation:
A triangle has 180 degrees in total. One of the angles are 145 degrees, so we can subtract and get 35 degrees. Then, it says that the remaining angles are in a ratio 2:3. So, we would have:
[tex]2x:3x = 35 \\2x+3x = 35\\5x=35\\x=7[/tex]
Now that we know what x is, we can multiply that to our ratio:
[tex]2\cdot7=14 \text{ degrees for the first angle}\\3\cdot7=21 \text{ degrees for the second angle }[/tex]

4x – 5 = 2(2x + 1) Please help plss
Answer:
0=7
Step-by-step explanation:
Distribute
4−5=2(2+1)
4−5=4+2
Add 5 to both sides of the equation
4 − 5 = 4 + 2
4 − 5 + 5 = 4 + 2 + 5
Simplify Add the numbers
Add the numbers
4 = 4 + 7
Result
0=7

5. The graph of a function is a line that
passes through the coordinates (2, 11)
and (8, 14).
Write an equation in the form
y = mx + b for this function.
Answer:
y = 1/2x + 10
Step-by-step explanation:
(y-11)/(14-11) = (x-2)/(8-2)
(y-11)/3 = (x-2)/6
2y-22 = x-2
2y = x + 20
y = 1/2x + 10
Let m = slope of the line.
m = (14 - 11)/(8 - 2)
m = 3/6
m = 1/2
We now have the slope and the slope is 1/2.
We plug the slope and one of the point into the point-slope formula.
Here is the point-slope formula:
y - y_1 = m(x - x/_1)
I will use the point (2, 11).
y - 11 = (1/2)(x - 2)
y - 11 = (1/2)x - 1
Now we solve for y by adding 11 to both sides of the equation.
y = (1/2)x - 1 + 11
Answer: y = (1/2)x + 10

What is the property of a straight angle?The property of straight angle says that, the angle of a straight line is equal to the 180 degrees.
It can also be define as the sum of all the angle made on the straight line is equal to the 180 degrees.
For the first problem, the line GE, which is the diameter of the circle has two angles over it (x-3) degree and (12x-25) degrees.
For the diameter GE the sum of these two angle will be equal to 180 degrees. Thus,
[tex](x-3)+(12x-25)=180\\x-3+12x-25=180\\13x-28=180\\13x=180+28\\x=\dfrac{208}{13}\\x=16^o[/tex]
The value of mDE will be equal to (12x-25) as it is verticle angle of mGF. Thus,
[tex]arcDE=(12x-25)\\arcDE=(12(16)-25)\\arcDE=167^o[/tex]
Similarly the value of mEF
[tex]arcEF=(x-3)\\arcEF=(16-3)\\arcEF=13^o[/tex]
Let the radius of the circle is R. Then the measure of arc DFG is equal to the sum of areDEF and arc GF. Thus,
[tex]arcDFG=\dfrac{2\pi R}{2}+\dfrac{2 \pi R \angle GHF}{360}\\arcDFG=\dfrac{2\pi R}{2}+\dfrac{2 \pi R (167^o)}{360}\\arcDFG=6.056R[/tex]
For the second problem, the angle MN and QO are equal due to the vertical angle property. Therefore,
[tex](10x-45)=(6x-1)\\10x-6x=-1+45\\4x=44\\x=11[/tex]
The value of mMN is,
[tex]MN=(10x-45)\\MN=(10(11)-45)\\MN=65^o[/tex]
The value of NP using the property of straight line for line segment MP can be given as,
[tex]NP=180-MN\\NP=180-65\\NP=115^o[/tex]
Thus, the value of x is 16 degrees and the measure of the arc DFG for circles of homework 2 are 1 6.056 times radius of circle.

Answer:
C
Step-by-step explanation:
Clustered data emerge when the data from the entire sample can be grouped into a variety of different categories, refers to as clusters. Each cluster involves numerous observations, giving the data a “clustered” or “hierarchical” structure, with each observations encapsulated within the cluster.
Also, if we plot a series of numbers on a graph and we will see several of our dots gathered together, we have a cluster
From the above definition of clustered data the only option that is fitting into it is option C .

I think number 5 is 49 I'm not for sure about this one.
Step-by-step explanation:
Number 7:
Since it's a 90 degree angle, you just add 19 + 23 which gives you 42. Subtract 42 from 90 and it gives you 48, the value of the variable.
Number 5:

Two small bubbles that each have a radius of 3
centimeters collide and merge into one large bubble. The area of
the large bubble is equal to the sum of the areas of the two small
bubbles. To the nearest centimeter, what is the radius of the large
bubble?
Use 3.14 for Pi
find area of 1 small bub
πr² = 3.14 × 3²
= 28.26 cm
area of 2 small bub
28.26 × 2 = 56.52 cm
area of big bub = area of 2 small bub
= 56.52
find radius by using formula
πr² = 56.52
r² = 56.52 ÷ 3.14
r² = 18
r = √18
r = 4.24 cm
round off to nearest cm
4.24 ≈ 4 cm
