What is the value of x?

OpenStudy (anonymous):

OpenStudy (anonymous):

27 19 17 23

OpenStudy (anonymous):

Your pic isnt clear ...

OpenStudy (unklerhaukus):

Alternate angles are equal

|dw:1379319399497:dw|

OpenStudy (anonymous):

It is the picture from the question.

OpenStudy (anonymous):

@.Sam.:can u see that ??? Exelent !:

OpenStudy (unklerhaukus):

OpenStudy (anonymous):

Yeah, sorry guys, You would think that they would blow it up more.

OpenStudy (anonymous):

heh !

OpenStudy (unklerhaukus):

one of the angles is \(5x-20\) and the other is \(3x+16\) use properties of alternate angles to set up an equation then solve the equation for \(x\)

OpenStudy (anonymous):

Alright, I am sure I can do this

OpenStudy (anonymous):

any problem ?:)

OpenStudy (anonymous):

5x - 20, I got x = 15

OpenStudy (anonymous):

WAIT, I might was suppose to add.

OpenStudy (anonymous):

so x = 25

OpenStudy (unklerhaukus):

\[5x =\color{red}{\cancel{\color{black}{5+x}}}\\ \quad= 5\times x\]

OpenStudy (anonymous):

What do I do next?

OpenStudy (unklerhaukus):

you need to set up an equation

OpenStudy (unklerhaukus):

What are two things that are equal in the question ?

OpenStudy (anonymous):

X?

OpenStudy (unklerhaukus):

huh?

OpenStudy (anonymous):

I have no clue, I am confused, I am sorry.

OpenStudy (unklerhaukus):

what infomation does the picture give you?

OpenStudy (anonymous):

The two equations on lines that are parallel to each other

OpenStudy (unklerhaukus):

well there arnt any equals signs in the picture , so there arnt any equation

OpenStudy (unklerhaukus):

angles?

OpenStudy (anonymous):

There are acute angles?

OpenStudy (unklerhaukus):

yeah,

OpenStudy (unklerhaukus):

can you see how the angles are 'alternate angles'

OpenStudy (anonymous):

Not really, I don't too much get it. It's almost six in the morning, and this is the last question lol, so I am trying, sorry about being hard to deal with.

OpenStudy (unklerhaukus):

if there are some parallel lines |dw:1379322160440:dw|

OpenStudy (unklerhaukus):

and some intersecting lines |dw:1379322207023:dw|
