@snowflake0531

snowflake0531:

the two angles are equal 2x+6= x+9

xXQuintonXx:

ughhhh???? wrong problem xd

xXQuintonXx:

that was the other one snow lol

Meticulous:

The angles shown are corresponding angles

snowflake0531:

o-o lol

Meticulous:

if you didn't know corresponding angles are congruent. That being said you could create an equation to solve for x . Do you know how to create an equation knowing that the two angles are congruent?

xXQuintonXx:

._. ya lost me, maybe but i dont remember

Meticulous:

ok so the angle that is defined by the expression "2x + 24" and the angle that is defined by the expression "3x - 26" are corresponding angles which are equal to each other. Knowing that they are EQUAL to each other, we want to create an equation so we can solve for x

xXQuintonXx:

how would i do that? would i combine like terms?

Meticulous:

not exactly. The expressions are EQUAL to each other because the angles are congruent So the equation would be 2x + 24 = 3x - 26 because they are equal to each other

xXQuintonXx:

so the expression is 2x + 24 = 3x - 26

xXQuintonXx:

so do i have to make both sides equal 180?

Meticulous:

No, you would then want to solve for x using basic algebra

Meticulous:

Do you remember how to do that?

xXQuintonXx:

nope ._.

xXQuintonXx:

do i make it so they all = 180?

Meticulous:

No, the expressions are equal to each other. So you want to make 2x + 24 equal to 3x - 26

xXQuintonXx:

so they both have to = the same number?

Meticulous:

Correct!

Meticulous:

We can do this by solving for x in the equation created (2x + 24 = 3x - 26)

Meticulous:

So you said you don't remember how to solve for x, right?

xXQuintonXx:

x=50

Meticulous:

Yes! Well done!

xXQuintonXx:

thanks xd
