Let a = one angle \n" ); document.write( "Let b = the other \n" ); document.write( "From the problem statement we have \n" ); document.write( "(1) a + b = 180 \n" ); document.write( "and \n" ); document.write( "(2) (a+b) - (a-b) = 116 \n" ); document.write( "Simplifying (2) we get \n" ); document.write( "(3) 2*b = 116, or \n" ); document.write( "(4) b = 58 \n" ); document.write( "Then from (1) we get \n" ); document.write( "(5) a = 122 \n" ); document.write( "Let's use (2) to check our answer. \n" ); document.write( "Is ((122+58) - (122-58) = 116)? \n" ); document.write( "Is (180 - 64 = 116)? \n" ); document.write( "Is (116 = 116)? Yes \n" ); document.write( "Answer: The two angles are 122 degrees and 58 degrees. \n" ); document.write( " \n" ); document.write( " |
