Algebra.Com's Answer #304691 by rwm(914)![]() ![]() ![]() You can put this solution on YOUR website! A quad's angles total 360. \n" ); document.write( "a quad has 4 angles. Two sets of two which are equal\r \n" ); document.write( "\n" ); document.write( "so we have 2*3x+2*(4x+12)=360 \n" ); document.write( "6x+8x+24=360 \n" ); document.write( "14x=360-24 \n" ); document.write( "14x=336 \n" ); document.write( "7x=118 \n" ); document.write( "x=24 \n" ); document.write( "one angle is 3x=3*24=72 \n" ); document.write( "the other is 4x+12=4*24+12=96+12=108 \n" ); document.write( "so we have 72, 108, 72, 108\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
