if you have parallel lines, you can move them together and they coincide (are the same) and then you can compare corresponding angle names |dw:1370534963328:dw|

OpenStudy (amistre64):

also recall the the total degree of a straight line is 180 ...

OpenStudy (anonymous):

so would x also equal to 54

OpenStudy (amistre64):

yes

OpenStudy (amistre64):

and w+x = 180

OpenStudy (anonymous):

so then w=108

OpenStudy (amistre64):

well, w = 180 - x = 180 - 54 = 126

OpenStudy (anonymous):

oops I did my math wrong

OpenStudy (amistre64):

some things to keep in mind in general .... |dw:1370535314225:dw|
