Answer:
110
Step-by-step explanation:
Y and X have to equal 180
70+x+180
=110
Answer:
Option A (2197 cm³)
Step-by-step explanation:
For a cube with length of each side "a" , it's
- Total Surface Area = 6a²
- Volume = a³
_____________________________________________
According to the question ,
Total Surface Area = 1014 cm²
Let the length of each side of cube be 'a'.
Using the formula ,
![6a^{2} =1014](https://tex.z-dn.net/?f=6a%5E%7B2%7D%20%3D1014)
![=> a^{2} =\frac{1014}{6} = 169](https://tex.z-dn.net/?f=%3D%3E%20a%5E%7B2%7D%20%3D%5Cfrac%7B1014%7D%7B6%7D%20%3D%20169)
![=> a = \sqrt{169} = +13 \: or -13](https://tex.z-dn.net/?f=%3D%3E%20a%20%3D%20%5Csqrt%7B169%7D%20%3D%20%2B13%20%5C%3A%20or%20%20-13)
But length can't be negative . So , length of each side = 13 cm
∴ Volume of cube = 13³ = 2197 cm³

Answer: Vertical angles</h3>
Explanation:
Ignore the ray that angles 2 and 3 are adjacent to. It might help to copy the drawing but erase that ray in question. All we really care about is the X shape the two lines form along with angles 1 and 4. These two angles are opposite one another. We consider them vertical angles. They don't have to align vertically. They simply have to be opposite one another like this in this X configuration. Vertical angles are always congruent to one another.
P80 = 36 * 0.80 = 28.8
The above equation shows that the 80th percentile will have 28.8 values below it. So obtaining the 29th value will be the 80th percentile.
Looking at the given values, P80 = 67.
