Decagon is a regular polygon with 10 sides. The correct option that fills up the blanks is given by: Option C: 36°, 72°, 10, 5
What is a decagon?A decagon is a regular polygon with 10 sides.
As shown in the diagram attached below, the angle between two line segments connecting center and two adjacent vertex is of 36°.
Since rotating the decagon by that angle will land it in an unidentifiable way, as it looks alike, thus, rotating the decagon by a multiple of __36°__ carries the decagon onto itself.
Therefore, a rotation of _36 degree or 72 degree or any multiple of 36 degree__ counterclockwise will carry the decagon onto itself.
If we connect one vertex to opposite one, and flip it on that connecting line(this flip is called reflection), then the decagon will look same as before reflection.Thera are 5 such different lines.
Now in addition, we can connect lines from mid point of 1 side to other opposite side too. And this also can be done in 5 ways. On these connecting lines too, the decagon can be reflected onto itself.
Thus, we can reflect the decagon _5+5=10_ different ways. (these are the only ways, and it can be proven mathematically).
And including __5__ ways using the lines of symmetry that pass through the midpoints of two opposite sides
Thus, the correct option that fills up the blanks is given by: Option C: 36°, 72°, 10, 5

Answer:
1/8
Step-by-step explanation:
To find out, divide 1/3 by 8/3.
(1/3)/(8/3) = 1/8
8/3 goes into 1/3 exactly 1/8 times.
__
There are (at least) two ways to divide fractions.
1. "invert and multiply" (A.K.A. "swap dot")
[tex]\dfrac{1}{3}\div\dfrac{8}{3}=\dfrac{1}{3}\cdot\dfrac{3}{8}=\dfrac{1\cdot3}{3\cdot8}=\boxed{\dfrac{1}{8}}[/tex]

2. Drop common denominators.

The first sequence rule is subtract 8 starting from 72. The second sequence rule is subtract 6 starting from 58. What is the first number that appears in both sequences?
Question 2 options:
16
40
46
52
Answer:
A) 16
Step-by-step explanation:
1st sequence: 72-8x
2nd sequence: 58-6x
Set both sequences equal to each other and solve for x:
72-8x=58-6x
14-8x=-6x
14=2x
7=x
x=7
Plug x=7 back into the equation:
72-8(7)=58-6(7)
72-56=58-42
16=16
So the first number that appears in both sequences is 16.

Answer:
200 m^3
Step-by-step explanation:
1) find the side of the base
side = 40 : 4 = 10 m
2) find the base area
base area = side^2 = 10^2 = 100 m^2
3) find the Volume
V = (base area x height)/3 = (100 x 6)/3 = 200m^3

in a population of grasshoppers, the ratio of grasshoppers with a white marking to those without a white marking is 2:3. An entomologist captures and photographs 290 grasshoppers. How many photographs are likely to show grasshoppers with a white marking?
A. 193
B. 58
C. 112
D. 116
Answer:
D. 116
Step-by-step explanation:
Let the grasshoppers with a white marking be 2x.
Let the grasshoppers without a white marking be 3x.
2x + 3x = 290
5x = 290
x = 290 / 5
x = 58
The grasshoppers with a white marking
= 2x
= 2 ( 58 )
= 116

Find the value of y. Geometry, plz only answer if you know how to do it ! thanks
Answer:
y = 96
Step-by-step explanation:
In order to find y we have to find the value of x
angle "x" is an angle formed by a tangent line and a secant line.
Kindly look at the image.
As you can see an angle formed by a tangent and a secant is equal to half of its intercepted arc.
x's intercepted arc has a measure of 168
So...
X = [tex]\frac{168}{2}[/tex]
[tex]\frac{168}{2} =84[/tex]
So x = 84
Now to find y.
Angle "x" and angle "y" are formed on a straight line.
Angles formed on a straight line add up to equal 180°
That being said we can find a missing angle ( y ) by subtracting the given angle's measure ( angle x which has a measure of 84°) from 180
so y = 180 - 84
180 - 84 = 96
Hence y = 96

Step-by-step explanation:
hope this helps
Answer:
x= 6 and y= -1
Step-by-step explanation:
-2x - 9y = -3
-7x - 9y = -33
I'm going to be solving by elimination. However, you can solve using substitution as well.
So the first step is to eliminate one of the variables. In my opinion, what's easiest is eliminating the y variables. To eliminate you want to variables (that are the same) to equal 0 and cancel out. To do this, all I have to do is subtract. When I subtract I get 0 as shown below. I will also subtract the other variables and numbers in the equations because that's how elimination works.
-2x - 9y = -3
-7x - 9y = -33
5x = 30
-2 - (-7)=5 and -3 - (-33)= 30
There's no solution for the y variable because -9 - (-9)=0, which cancels out so it doesn't have to be written.
after that you get x=6 because you divide by 5 on both sides.
All that's left is to plug in 6 to one of the equations:
-2(6) - 9y= -3
-12 - 9y= -3
+12 +12
-9y= 9
Divide both sides by -9 to get y= -1

Answer:
b=18.76
Step-by-step explanation:
Let the line that splits the big triangle into two small triangles be x.
Let the unmarked side of the big triangle be y.
Consider the big triangle. By Pythagorus:
(6+16)²=b²+y²
484=b²+y²
y²=484-b²
Consider the small left triangle. By Pythagorus:
y²=6²+x²
y²=36+x²
x²=y²-36
Consider the small right triangle. By Pythagorus:
b²=16²+x²
b²=256+x²
b²=256+x²
b²=256+y²-36
b²=220+y²
b²=220+484-b²
2b²=704
b²=352
b=18.7616630393
b=18.76

Answer:
1. 42
2. 46
3. 0
Step-by-step explanation:
math
Answer:
1. x = 42
2. y = 46
3. z = 0
Step-by-step explanation:
1. 45 + x = 87
subtract 45 from both sides
x = 42
2. y - 31 = 15
add 31 to both sides
y = 46
3. 5z = 0
divide 5 from both sides
z = 0/5
since any fraction with a numerator of 0 is equal to 0, we get
z = 0
