$\"A%2BB=180\"$ ---------------> working eqn
\n" ); document.write( " $\"B\"$ is a supplement of $\"A\"$ where $\"A=3B-12\"$ ----> $\"highlight%28condition%29\"$ , 3 times its supplement less 12deg.
\n" ); document.write( "So go back wworking eqn:
\n" ); document.write( " $\"3B-12%2BB=180\"$
\n" ); document.write( " $\"4B=180%2B12\"$ ----> $\"4B=192\"$
\n" ); document.write( " $\"cross%284%29B%2Fcross%284%29=cross%28192%2948%2Fcross%284%29\"$
\n" ); document.write( " $\"B=48deg\"$
\n" ); document.write( "go back working eqn to get $\"A\"$ ;
\n" ); document.write( " $\"A%2B48=180\"$
\n" ); document.write( " $\"A=180-48=132deg\"$
\n" ); document.write( "In doubt? go back to the $\"highlight%28condition%29\"$ :
\n" ); document.write( " $\"132=3%2848%29-12\"$
\n" ); document.write( " $\"132=144-12\"$
\n" ); document.write( " $\"132deg=132deg\"$
\n" ); document.write( "Thank you,
