Answer:
To figure out the total measure of the angles for a 27-gon, there is a formula.
n - 2 x 180* (n is the number of sides, which would be 27)
27 - 2 = 25
25 x 180* = 4500*
The total measure of the angles of a 27-gon is: 4500*

Answer:
Step-by-step explanation:
36 + b > -24b + (-64)
24b + b > -36 - 64
25b > 100
b > 100/25
b > 4
First take the inside diameter and divide by 2 to get the radius (4cm)
Then use
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
r^2 with 'r' being your radius to get the area of the base
The area is 12.7 cm
Now multiply the height by the area of the base to get the volume/ capacity!
40cm x 12.7cm (rounded to the nearest tenth) = 502.7 cubic centimeters
![\frac{3(x+5)}{2} \cdot 2=21\cdot 2](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%28x%2B5%29%7D%7B2%7D%20%5Ccdot%202%3D21%5Ccdot%202%20)
Above step we use "Multiplication property of equality"
![3(x+5)=42](https://tex.z-dn.net/?f=%203%28x%2B5%29%3D42%20)
In the above step we "Simplify on both sides of equation"
![3x+15 = 42](https://tex.z-dn.net/?f=%203x%2B15%20%3D%2042%20)
In the above step we use "Distribution property"
![3x+15-15=42-15](https://tex.z-dn.net/?f=%203x%2B15-15%3D42-15%20)
The above step is the result of using "Subtraction property of equality"
![3x=27](https://tex.z-dn.net/?f=%203x%3D27%20)
Above step is result of "Combining the like terms"
![\frac{3x}{3} =\frac{27}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3x%7D%7B3%7D%20%3D%5Cfrac%7B27%7D%7B3%7D%20%20)
Above step is the result of using "Division property of equality"
![x=9](https://tex.z-dn.net/?f=%20x%3D9%20)
Above step is result of "Simplifying fractions on either side of equation"
