X=7 you use proportions. If you take one side length, such as 24 and 32 you will see that the polygon with a side of 24 is 3/4 the length of the polygon of 32. So you can say that 6/? = 3/4. Since 3 is half of 6, we can double 3 and 4 to get 6/8. Since the length of the side is subtraction of one, it would be 7

Look at the left side of the polygon. Since they are both real numbers, we can use those to set up a proportion:

16:12=(x-1):6


Now, we can cross multiply and solve:
96=12(x-1)
96=12x-12
108=12x
9=x

The value of x is 9

Hope this helped!

Answer:

x=14

Step-by-step explanation:

8x-9+6x-7 = 180 (being adjacent angles)

14x-16 = 180

14x = 180+16

14x =196

x = 196/14

x =14

please mark me brainliest.

Find the circumference pls help.
Triss [41]
Equation for circumference is c = 2(pi)r

r = 1/2(d)

d = 20

So…. r = 1/2(20) = 20/2 = 10

Going back to circumference equation

c = 2(pi)(10) = 2(3.14)(10) = 62.8

PLEASE HELP ME!
arlik [135]

Answer:

Angle: 22.5 deg, Complement: 67.5 deg, Supplement: 157.5 deg

Step-by-step explanation:

22.5 is 1/3 of 67.5

so compliment is 67.5.

Supplement is just adding another angle so I chose 7.

I did 22.5 x 7 = 157.5

Another example would be:

Angle: 10 deg, Complement: 30 (because 10 x 3), Supplement: 70 (because 10 x 7)

Hope this helps :)
