Algebra.Com's Answer #10012 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! THE RULE IS THAT IN A TRIANGLE , SUM OF ANY 2 SIDES SHOULD BE GREATER THAN THE THIRD SIDE.SO THE ANSWER IS D,THAT IS 8,SINCE WITH,7,10 AND 8 WE HAVE \n" ); document.write( "7+10>8,7+8>10 AND 8+10>7 \n" ); document.write( "A)17 IS NOT CORRECT BECAUSE 7+10=17...SUM OF 2 SIDES IS NOT GREATER THAN THE THIRD SIDE \n" ); document.write( "B)20 IS NOT CORRECT BECAUSE 7+10=17<20....SUM OF 2 SIDES IS NOT GREATER THAN THE THIRD SIDE \n" ); document.write( "C)3 IS NOT CORRECT BECAUSE 7+3=10... SUM OF 2 SIDES IS NOT GREATER THAN THE THIRD SIDE \n" ); document.write( " |
