\n" ); document.write( "F+S+T=180
\n" ); document.write( "F+3F-8+7F+1=180
\n" ); document.write( "11F=180+8-1
\n" ); document.write( "11F=187
\n" ); document.write( "F=187/11
\n" ); document.write( "F=17 DEGREES FOR THE FIRST ANGLE.
\n" ); document.write( "S=3*17-8
\n" ); document.write( "S=51-8
\n" ); document.write( "S=43 DEGREES FOR THE SECOND ANGLE.
\n" ); document.write( "T=7*17+1
