Algebra.Com's Answer #175710 by Photonjohn(42)![]() ![]() ![]() You can put this solution on YOUR website! Use the law of cosigns \r \n" ); document.write( "\n" ); document.write( "b^2 = a^2 + c^2 - 2acCosign(25)\r \n" ); document.write( "\n" ); document.write( "You will find a quadratic equation exists with a= a negative and a positive number. The positive number is too large to make the triangle real, i.e. a is greater than the sum of b + c. therefore the triangle doesn't exist.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
