Let angle B=x\r
\n" ); document.write( "\n" ); document.write( "so angle A +angle B + angle C =180
\n" ); document.write( "so 3x+x+(90-x)=180 then 3x+90=180 then x=30 \r
\n" ); document.write( "\n" ); document.write( "angle B =30 degrees, angle A=90 degrees and angle C= 60 degrees
\n" ); document.write( "
\n" );
