Algebra.Com's Answer #183172 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! To find the hypotenuse when side a=7, b=3, c= ? . So, a=49, b=9, c=the square root of 58 which is 7.6 according to a calculator, my question is how is the .6 derived solving this by longhand??? \n" ); document.write( "---------------- \n" ); document.write( "c = sqrt(49+9) \n" ); document.write( "c = sqrt(58) \n" ); document.write( "c = sqrt(2*29) \n" ); document.write( "c = sqrt(2)*sqrt(29) \n" ); document.write( "Both of these sqrt's are irrational (endless non-repeating decimals) \n" ); document.write( "You can approximate the answers in decimal form but you cannot ever \n" ); document.write( "completely evaluate them in decimal form. \n" ); document.write( "============================================= \n" ); document.write( "sqrt(58) = 7.6158.....endlessly \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
