Algebra.Com's Answer #192231 by drk(1908)![]() ![]() ![]() You can put this solution on YOUR website! WIth 2 sides known, we can use the following to estimate the third side: \n" ); document.write( "5-3 < x < 5+3 \n" ); document.write( "2 < x < 8 \n" ); document.write( "using 3 as the third side, perimeter = 11 \n" ); document.write( "using 7 as the third side, perimeter = 15. \n" ); document.write( "so our only answer is 12, [C] \n" ); document.write( " |
