(x+20),(x), and (x-50)
\n" ); document.write( "x+20+x+x-50=180
\n" ); document.write( "3x=180-20+50
\n" ); document.write( "3x=210
\n" ); document.write( "x=210/3
\n" ); document.write( "x=70 ans.
\n" ); document.write( "70+20=90 ans.
\n" ); document.write( "70-50=20 ans
\n" ); document.write( "Proof:
\n" ); document.write( "70+90+20=180
