<span>Each Exterior Angle = (360 degrees) ÷ (Number of Sides)
</span>
A pentagon has 5 sides so

<span>Each Exterior Angle = 360 / 5
</span>
Each Exterior Angle =72
If the exterior angle = 2x and the angle = 72 degrees then
2x = 72 and 
x = 36

Answer:

x = 36° .

Step-by-step explanation:

Given : One exterior angle of a regular pentagon has a measure of (2x).

To find :  what is the value of x.

Solution : We have given

One exterior angle of a regular pentagon has a =  (2x).

Each exterior angle = \frac{360}{number\ of\ exterior\ angle}.

Plug the values each exterior angle = 2x , number of exterior angle = 5.

2x = \frac{360}{5}.

2x = 72.

On dividing both sides by 2

x = 36.

Therefore, x = 36° .

In which number does the digit 2 have a value that is ten times as great as the value of the digit 2 in the number 135,284?
Valentin [98]

Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

First and foremost, we should note that the value of the digit 2 in the number 135,284 is 200. Therefore, the value that is ten times as great as the value of the digit 2 in the number 135,284 would be:

= 10 × 200

= 2000

Therefore, the 2 must be in the thousands place. This can be seen in numbers such as:

172748.

ipn [44]

Answer:

\frac{19}{7}x+\frac{11}{7}y+5=0

Step-by-step explanation:

the intersection of x-2y=0 and 3x+y+5 is (\frac{-10}{7};\frac{-5}{7})

=> the line : \frac{19}{7}x+\frac{11}{7}y+5=0
