x=2(180-x)-45
\n" ); document.write( "x=360-2x-45
\n" ); document.write( "x+2x=315
\n" ); document.write( "3x=315
\n" ); document.write( "x=315/3
\n" ); document.write( "x=105 degrees.
\n" ); document.write( "Proof:
\n" ); document.write( "105=2(180-105)-45
\n" ); document.write( "105=2*75-45
\n" ); document.write( "105=150-45
\n" ); document.write( "105=105 \n" ); document.write( "
