That means x+y = 90 by definition.\r \n" ); document.write( "\n" ); document.write( "Let x be one angle. Let y be the other angle.\r \n" ); document.write( "\n" ); document.write( "We know that y = 18+2x\r \n" ); document.write( "\n" ); document.write( "Then x + 18 + 2x = 90\r \n" ); document.write( "\n" ); document.write( "3x = 72\r \n" ); document.write( "\n" ); document.write( "x = 24\r \n" ); document.write( "\n" ); document.write( "If x = 24, then 24+y = 90 y = 66\r \n" ); document.write( "\n" ); document.write( "24,66 \n" ); document.write( " |
