x = 36

pentagon has 5 sides . The formula n/360 gives you the measure of each angle in a regular polygon. So in this case n ( stands for number of sides) is 5. Sum of exterior angle of a any polygon is 360. The measure of 1 exterior angle is given. It is 2x.

Now using ALGEBRAIC EXPRESSIONS we can write it as 5/360 = 2x

which is 72=2x

which is 72/2 = x

which is 36 = x

so x = 36.

navik [9.2K]

The property displayed here is the distributive property.

If you have a variable or unknown number inside or outside of parentheses, you can distribute it to each term and add the terms together, and it will remain true.

Example:

4(x + 5)

After distributing, it'll look like this:

4x + 20

Answer:

558 cm^3

Step-by-step explanation:

V cone = 1/3 pi r^2 h

We know it is  186 cm^3

186 =1/3 pi r^2 h

Multiply by 3

558 = pi r^2 h


V cylinder = pi r^2 h

From above we know that pi r^2 h is 558 , so the Volume of  the cylinder is 558 cm^3
