X+3X+X+55=180
\n" ); document.write( "5X=180-55
\n" ); document.write( "5X=125
\n" ); document.write( "X=125/5
\n" ); document.write( "X=25 DEGREES FOR THE FIRST ANGLE.
\n" ); document.write( "3*25=75 DEGREES FOR THE SECOND ANGLE.
\n" ); document.write( "25+55=80 DEGREES FOR THE THIRD ANGLE.
\n" ); document.write( "PROOF:
\n" ); document.write( "25+75=80=180
\n" ); document.write( "180=180
\n" ); document.write( "
