Algebra.Com's Answer #227600 by mananth(16946) You can put this solution on YOUR website! the largest angle be x deg \n" ); document.write( "one angle = x-10 \n" ); document.write( "second angle = x-20 \n" ); document.write( ".. \n" ); document.write( "x+x-10+x-20=180 \n" ); document.write( "3x-30=180 \n" ); document.write( "3x=180+30 \n" ); document.write( "3x=210 \n" ); document.write( "x=70 deg \n" ); document.write( "the other angle will be 70-10=60deg \n" ); document.write( "third angle = 70-20=50deg \n" ); document.write( " \n" ); document.write( " |
