1. $\"A%2BS=180\"$
\n" ); document.write( "2. $\"A=S-40\"$
\n" ); document.write( "Substitute eq. 2 into eq. 1,
\n" ); document.write( " $\"%28S-40%29%2BS=180\"$
\n" ); document.write( " $\"2S-40=180\"$
\n" ); document.write( " $\"2S=220\"$
\n" ); document.write( " $\"highlight%28S=110%29\"$ degrees
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"A=110-40\"$
\n" ); document.write( " $\"highlight%28A=70%29\"$ degrees \n" ); document.write( "
