Let $\"+x+\"$ = the degrees in the 1st angle
\n" ); document.write( "The sum of the angles of a triangle is always 180
\n" ); document.write( "given:
\n" ); document.write( " $\"+x+%2B+2x+%2B+5+%2B+3x+-+35+=+180+\"$
\n" ); document.write( " $\"+6x+-+30+=+180+\"$
\n" ); document.write( " $\"+6x+=+210+\"$
\n" ); document.write( " $\"+x+=+35+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+2x+%2B+5+=+2%2A35+%2B+5+\"$
\n" ); document.write( " $\"+2x+%2B+5+=+75+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+3x+-+35+=+3%2A35+-+35+\"$
\n" ); document.write( " $\"+3x+-+35+=+105+-+35+\"$
\n" ); document.write( " $\"+3x+-+35+=+70+\"$
\n" ); document.write( "The angles are 35, 75 and 70
\n" ); document.write( "check:
\n" ); document.write( " $\"+35+%2B+75+%2B+70+=+180+\"$
\n" ); document.write( " $\"+180+=+180+\"$
\n" ); document.write( "OK
\n" ); document.write( " \n" ); document.write( "

\n" );
