B=C
\n" ); document.write( "A=B+141 OR A-B=141
\n" ); document.write( "A+B+C=180
\n" ); document.write( "A+2B=180
\n" ); document.write( "-(A-B=141) SUBTRACT THESE TWO EQUATIONS
\n" ); document.write( "----------------------
\n" ); document.write( "2B+B=39
\n" ); document.write( "3B=39
\n" ); document.write( "B=39/3
\n" ); document.write( "B=13 DEGREES. C=13 DEGREES.
\n" ); document.write( "A=13+141
\n" ); document.write( "A=154 DEGREES.
\n" ); document.write( "PROOF:
\n" ); document.write( "154+13+13=180
