Find the value of x. Then find the measure of each labeled angle.
adell [148]

Answer:

x = 111

Step-by-step explanation:

x + x - 42  = 180     {Lines are parallel. So, they are supplementary}

2x - 42 = 180  

Add 42 to both sides

2x - 42 + 42 = 180 + 42

               2x = 222          {Divide both sides by 2}

                 x = 222/2

x = 111

<h2>Repeating Decimal to Fraction</h2>

Note: "..." is the repeating sign I'm using.

Answer: 2/9

<h3>Steps</h3>

Let X equal the decimal number  

Equation 1:

X = 0.2...

With 1 digit in the repeating decimal group,

create a second equation by multiplying

both sides by 10

X * 10 = 10X and 0.2...* 10 = 2.2...

Equation 2:

10X = 2.2...

Subtract equation 1 from equation 2

10X = 2.2...  -   X = 0.2...

We get

9X = 2

In conclusion, 0.2... =   2/9

<h2>Repeating Decimal to Mixed Number</h2>

This decimal cannot be a mixed number because it has no number in the one's, ten's, or hundred's place.
