Answer:
x = 85
Step-by-step explanation:
To solve, first find the angle of the other missing angle in the left by subtracting the outside angle from 180:
180 - 155 = 35
Then add this and the known angle:
35 + 60 = 95
Then subtract this from 180 to get the missing angle for x:
180 - 95 = 85

I hope it helps!
4 and 5 are right, but 2 isn't because consonants are the opposite of vowels. So, you wouldn't use a or e.
Answer:
C
Step-by-step explanation:
Let's find the area of each of the two circles.
First Circle:
The first circle has a diameter of 10 inches. That means the radius is 5 inches. So, its area is:
![A=\pi r^2\\A=\pi (5)^2\\A=25\pi](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%5C%5CA%3D%5Cpi%20%285%29%5E2%5C%5CA%3D25%5Cpi)
Second Circle:
The second circle has a diameter twice that of the first. So, the diameter is 20 inches. This means that the radius is 10 inches. Find the area:
![A=\pi r^2\\A=\pi (10)^2\\A=100\pi](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%5C%5CA%3D%5Cpi%20%2810%29%5E2%5C%5CA%3D100%5Cpi)
Now, find the ratio between them by dividing:
![\frac{\text{Smaller}}{\text{Larger}}=\frac{25\pi}{100\pi}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BSmaller%7D%7D%7B%5Ctext%7BLarger%7D%7D%3D%5Cfrac%7B25%5Cpi%7D%7B100%5Cpi%7D)
Simplify:
![\frac{\text{Smaller}}{\text{Larger}}=\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BSmaller%7D%7D%7B%5Ctext%7BLarger%7D%7D%3D%5Cfrac%7B1%7D%7B4%7D)
1/4 is the same as 1:4
So, our answer is C :)
55% of 20 is 11. the answer is 20
