Answer:
8) interior angle = 160
9) x = 20
Step-by-step explanation:
8)
18-gon has 18 sides
The formula for sum of interior angles for an 18-gon is:
(18x180)-360 = 2880 degrees
2880 degrees / 18 angles = 160 degrees
9)
exterior angles = 360 degrees
360 = (3x-2)+(x+8)+(4x+9)+(2x-1)+(3x)+(4x+6)
360 = 3x-2+x+8+4x+9+2x-1+3x+4x+6
360 = 17x+20
17x = 340
x = 20 degrees
So I need 20 words but I don’t get why so here’s this useless sentence

The perimeters of two similar triangles are 25 cm and 15 cm respectively. If one side of the first
triangle is 9 cm, find the corresponding side of the second triangle.
plz guys hrlp me if you solve i will make brainliest
Answer:
5.4cm
Step-by-step explanation:
In similar triangles, the perimeter of the triangles will be in the ratio of their corresponding sides.
The ratio of their perimeter is
perimeterofΔ2 15
--------------------- = -------------
perimeterofΔ1 25
So, the side of triangle 2 will be
9 * 15 15
---------------- = --------------
sideofΔ2 25
=
⟹side of Δ2= 25 / 9∗15 =5.4.

(5)(4)(2)=40
area of 2 sides:
(x)(5)(2)=?
area of the other two sides:
(x)(4)(2)=?
total area=76
76=40+10x+8x
simplify:
36=18x
x=2

The function P(1) - 5,000(1.098)' models the value, in dollars, of a painting after t years. What is the initial value of the painting?
Answer:
the answer is $5,000
Step-by-step explanation:
the question is asking what the initial value of the painting is and in the equation, they are trying to find out how much the painting will cost after t years. the 1.098 is how much the painting decreases each year and it is being multiplied by &5000 so $5000 is the original value of the painting.

Answer:
5,720,000 Sq Feet.
Step-by-step explanation:
They are asking the Area of a Trapezoid
Equation =( base + base / 2) x height
Lets first set it up. We know that A-B is 200 feet. & D-C is 260. They are both the bases.
So if you multiply them (200 x 260) You will get 52000.
Now we divide that by 2. (52000 / 2 = 26000)
Now it says the straight line is 220. I think this refers to the height.
Now we multiply 26000 x 220. Which is 5720000.
Its a pretty big number, but that is the answer! :)
Hope this helps!
Solve for each variable X and Y.
Answer:
x=5 and y=7
Step-by-step explanation:
The opposite parallel sides of any rhombus are going to be equal.
a.) Knowing this you take (x+14) and make it equal to (5x-2). Then you subtract the x from (x+14), and add the 2 from (5x+2), making the new equation 16=4x. You divide 4 by x and by 16, getting the final simplified answer of x=4.
b.) Using the same method you take 3y-3 and set it equal to (2y+4). Then you subtract the 2y from (2y+4) and add the 3 from (3y-3) to bother sides. Now you have your new equation and answer being y=7.
a.) x+14 = 5x-2
b.) 3y-3 = 2y+4

please help(: ( 8th grade lesson)
Step-by-step explanation:
Since angle 1 is on a straight line and we know that angle 4 is 160, and a straight line has a sum of 180 degrees, simply subtract 160 from 180 to get angle 1.
Angle one would be 180-160 = 20
Since the sum of angles in a triangle is 180 and we already know 2 of them, angle 1 is 20 and angle 3 is 30, just add them together and then subtract that from 180. 20 + 30 = 50, and 180 - 50 = 130.
So in conclusion:
Angle 1 is: 20
Angle 2 is: 130

For which value of x will the rational expression below be undefined? Check all that apply. (x-5)(x+2)/x+1 A. -5 B. -1 C. 1 D. 5 E. -2 F. 2
Answer:
B. -1Step-by-step explanation:
Given expression:
(x-5)(x+2)/(x+1)This is undefined when the denominator is zero:
x + 1 = 0x = -1Correct choice is B
Answer:
Answer :-[tex] \sf \: \dfrac{(x - 5)(x + 2)}{x + 1} [/tex]
Now,
Taking denominator as 0
x + 1 = 0
x = 0 - 1
x = -1
Write an
equation of the line passing through the points (4,13) and (-1,- 12).
Answer:
Step-by-step explanation:
(-12 - 13)/(-1 - 4)= -25/-5 = 5
y - 13 = 5(x - 4)
y - 13 = 5x - 20
y = 5x - 7
Find two positive numbers satisfying the given requirements.
The product is 152 and the sum is a minimum.
Answer:
8 and 19
Step-by-step explanation:
To some this, let's first list all the factors of 152. They are;
1, 2, 4, 8, 19, 38, 76, 152.
Now, let's arrange them to reflect being multiplied to get 152.
Thus;
1 × 152 = 152
2 × 76 = 152
4 × 38 = 152
8 × 19 = 152
Also, let's do the same for their sum;
1 + 152 = 153
2 + 76 = 78
4 + 38 = 42
8 + 19 = 27
Looking at the figures above, the ones that their product is 152 but have the least sum are 8 and 19

Answer:
The Answer should be 9
140-180=40
360÷40=9
Answer:
9
Step-by-step explanation:
size of each interior angle can be represented by: [tex]140^{o} = 180^{o}[/tex]•[tex]\frac{(n-2)}{n}[/tex]
solve for n:
[tex]140^{o} = 180^{o}[/tex]•[tex]\frac{(n-2)}{n}[/tex] multiply both sides by n
140ºn = 180º(n - 2) distribute 180º to (n - 2)
140ºn = 180ºn - 360º subtract 180ºn from both sides
-40ºn = -360 divide both sides by -40º
n = 9
