An explanation would be nice too instead of just the answer.

OpenStudy (mikezack123):

do you know the rules of parallelograms?

OpenStudy (mikezack123):

consecutive angles are supplementary which means they add up to 180 degrees

OpenStudy (anonymous):

Okay, so then would I just do 42+(3x+6)=180?

OpenStudy (mikezack123):

yes i was just typing that

OpenStudy (mikezack123):

thats right, then solve for x

OpenStudy (anonymous):

Ok. :) Thank you!! That makes sense.

OpenStudy (mikezack123):
