X+(2X-20)+(3X-10)=180
\n" ); document.write( "6X-30=180
\n" ); document.write( "6X=180+30
\n" ); document.write( "6X=210
\n" ); document.write( "X=210/6
\n" ); document.write( "X=35 DEGREES.
\n" ); document.write( "2*35-20=70-20=50 DEGREES.
\n" ); document.write( "3*35-10=105-10=95 DEGREES.
\n" ); document.write( "PROOF
\n" ); document.write( "35+50+95=180
\n" ); document.write( "180=180
\n" ); document.write( "THIS IS AN OBTUSE TRIANGLE: A TRIANGLE WITH ONE ANGLE >90 DEGREES.
