x=10, y=20

Step-by-step explanation:

180-20-=160

160-90=7x

7x=70

x=10

5x+2y=90

5(10)+2y=90

50+2y=90

2y=40

y=20

Hope this helps! :)

Answer:

x=10     y= 20

Step-by-step explanation:

to find x use the 20* and the 90* from the top to get 110

then use the straight  line to subtract 110     180-110=70  

then do 70 / 7 =10

to find y solve for 5x first to get 50 add 70* from the vertical angle to get 120

then use the vertical angle from 20* to get 140

then use the straight line to subtract  140          180-140=40

then do 40/2 = 20

2. The measure of an interior angle of a regular polygon is 160 degrees. Find the number of sides in the
polygon

Answers

Answer:

18 sides

Step-by-step explanation:

(N x 180) - 360 = 160N

180N -360 = 160N

20N = 360

N = 18

Proof:

(18 x 180) -360 = 2880 total degrees

2880/18 sides = 160°

PLEASE HELP IF YOU CAN!! Use "completing square method" to write an equation for x² + 20x + 82 = -4 in prefect square form and solve for x

Answers

x^2 + 20x + 82 = -4

Subtract 82

x^2 + 20x = -86

CTS b/2 squared = 20/2 ^ 2 = 100

x^2 + 20x + 100 = -86 + 100
x^2 + 20x + 100 = 4
(x + 10)^2 = 4

Take the square root

x + 10 = +/- 2
x = -10 +/- 2

x = -10 + 2 = -8
x = -10 - 2 = -12

x = -8, -12

It was first used for cloth petticoats in the early 19th century. The word "crinoline" comes from the French words crin meaning horsehair and lin meaning linen. The full skirts with crinoline gave an illusion of extra width. In fact, as time progressed, the skirts became wider and appeared fuller. In 1856, metal cage crinoline was marketed in America, France, and Britain. It was the first fashion to be adopted by all classes in England and America. Working women did not care much about the cheap steel bands showing through the ridges of their skirts. Although the cage crinoline was awkward and caused damages to objects when women knocked them as they walked through, these remained popular for a long time. These skirts sometimes spanned over six feet and made walking through the doors challenging. Today, crinolines are usually a part of a formal outfit, such as an evening gown or a wedding dress. Instead of metal, the hoops are made of plastic or nylon. Modern crinolines are much more lightweight and flexible.What writing technique does the author use to organize this passage? A. The author classifies types of dresses to organize their types. B. The author defines the idea of fashion for high-class women. C. The author shows the cause and effect of using horsehair. D.
