Algebra.Com's Answer #7610 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! I would let x = the complement, since that is at the end of the first sentence. \n" ); document.write( "2x + 25 = the supplement\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The equation is based upon the fact that if you subtract the supplement minus the complement, you get 90 degrees. \n" ); document.write( "2x + 25 - x = 90 \n" ); document.write( "x + 25 = 90 \n" ); document.write( "x= 65 complement \n" ); document.write( "90-x = 25 = the angle \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "There may be easier ways to do this if we think about it, but at least this works to solve the problem. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "OH! I see it!! THE WAY YOU DID IT IS CORRECT!! YOU JUST FORGOT THE 25.\r \n" ); document.write( "\n" ); document.write( "Your equation: 180-x= 2(90-x) \n" ); document.write( " \n" ); document.write( "Should have been: 180-x= 2(90-x)+ 25\r \n" ); document.write( "\n" ); document.write( "This works!! x= 25. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "R^2 at SCC \n" ); document.write( " |
