document.write( "Question 700143: Hi, I was wondering there is two lines that form a perpendicular line that looks like an x and the top angle says (x+y+5) the left angle says y and the right angle says 2x. y and x+y+5 are supplementary and x+y+5 and 2x are supplementary. I already wrote out 2y+x+5=180 and then 3x+y=5=180 but I don't know how to solve it from there. \n" ); document.write( "
Algebra.Com's Answer #431814 by KMST(5328)![]() ![]() You can put this solution on YOUR website! You are right. \n" ); document.write( "The angles measuring (in degrees) \n" ); document.write( "so \n" ); document.write( "The angles measuring \n" ); document.write( "so \n" ); document.write( "Those two equations can be simplified a bit. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Then we would have the system of linear equations \n" ); document.write( " \n" ); document.write( "The solution is \n" ); document.write( "The three angle measures would be \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "ALTERNATE WAYS TO THE SAME SOLUTION: \n" ); document.write( "The left and right angles are vertical angles, so they have the same measure, \n" ); document.write( "and \n" ); document.write( "Then your system could be \n" ); document.write( " |
