We know the sum of the angels in a triangle is 180.\r \n" ); document.write( "\n" ); document.write( "Given: A = 2B + 20 \n" ); document.write( "Then C = 180 - A - B \n" ); document.write( "C = 180 - (2B+20) - B \n" ); document.write( "C = 180 - 2B - 20 - B \n" ); document.write( "C = 160 - 3B\r \n" ); document.write( "\n" ); document.write( "So, the angles are: \n" ); document.write( "A = 2B+20 \n" ); document.write( "B = B \n" ); document.write( "C = 160 - 3B\r \n" ); document.write( "\n" ); document.write( "Make sense? \n" ); document.write( " |
