What is the answer to this question?

Answers

Answer:

A = 139°

G = 41°

Step-by-step explanation:

Measure of D = 139°

Given that, X|| Y

Then

Alternate angle theorem (Remember that "Z" Theorem?)

< D = < H (By simple theorem above![Alt <s])

<H = 139°

Also <H = <A[Vertically opposite angles]

<A = 139°

We know by co-interior < theorem,[X||Y]

<H +<G = 180°
<G = 180° - <H = 180° - 139°
<G = 41°

A = 139 degrees
G = 41 degrees

12x−5y=−20
y=x+4

Answers

Answer:

12x-5(x+4)=-20

7x=0

x=0

so,y=4

ANSWER:

x=0

STEP BY STEP EXPLANATION:

1.) 12x-5y=-20
y=x+4

2.) 12x-5(x+4)=-20
*because you are taking the y= equation and putting that into 5y replacing the y.

3.) 12x-5x-20=-20
*because you multiply -5 by the x and the 4 and get -5x-20.

4.) 7x-20=-20
*because you subtract 5x from 12x because you are using like terms to make the equation smaller.

5.) 7x=0
*because you add the 20 on both sides to cancel out the 20 to get x closer to being by itself.

6.) x=0
*because you divide 7 on both sides to get x completely by itself.
