@TheSmartOne

OpenStudy (acxbox22):

looking only at lines l and n the 58 degree angle is alternate interior to angle x

Omg Sky Ferreira in that picture is perfect!

OpenStudy (winsteria):

@acxbox22 so how do I get the answer?

OpenStudy (winsteria):

yes she's perfect lol @Kyliejones

OpenStudy (anonymous):

Yes!

OpenStudy (acxbox22):

alternate interior angles are congruent since technically they are vertical angles

OpenStudy (winsteria):

so what's the value of x lol? @acxbox22

OpenStudy (acxbox22):

thats for you to find out lol

OpenStudy (acxbox22):

if we know x and the 58 degree angle are alternate interior angles and we know alternate interior angles are congruent what can we say about angle x?

OpenStudy (winsteria):

I don't know @acxbox22

OpenStudy (acxbox22):

hint: angle x is congruent to the 58 degree angle

jimthompson5910 (jim_thompson5910):

this hint might help

OpenStudy (acxbox22):

i wish i could explain as well as @jim_thompson5910 :(

jimthompson5910 (jim_thompson5910):

if we have two parallel lines like this |dw:1426812171176:dw|

jimthompson5910 (jim_thompson5910):

then add in a transversal cut |dw:1426812280102:dw|

OpenStudy (winsteria):

So x is 58? Idk?

jimthompson5910 (jim_thompson5910):

the corresponding angles (marked below) are congruent |dw:1426812303742:dw|

jimthompson5910 (jim_thompson5910):

yes x =58 because of this and because vertical angles are congruent one such pair of vertical angles are drawn below |dw:1426812341198:dw|
