Let x, y = angles of parallelogram.
\n" ); document.write( ".
\n" ); document.write( "sum of angles = 2x +2y = 360
\n" ); document.write( ".
\n" ); document.write( "but x=(2y-15),,,given
\n" ); document.write( ".
\n" ); document.write( "subst
\n" ); document.write( ".
\n" ); document.write( "2(2y-15) +2y =360
\n" ); document.write( ".
\n" ); document.write( "4y -30 +2y =360
\n" ); document.write( ".
\n" ); document.write( "6y =390
\n" ); document.write( ".
\n" ); document.write( "y= 65,,,,,,,x=2y-25 =2(65)-15 = 115
\n" ); document.write( ".
\n" ); document.write( "check 65 +115 = 180,,,ok both supplemental and 1/2 of 360
\n" ); document.write( ".
