Are the angles supplementary or complementary?
\n" ); document.write( "If they're supplementary,
\n" ); document.write( " $\"7x%2B12%2B3x%2B40=180\"$
\n" ); document.write( " $\"10x%2B52=180\"$
\n" ); document.write( " $\"10x=128\"$
\n" ); document.write( " $\"x=128%2F5\"$
\n" ); document.write( " $\"x=64%2F5\"$
\n" ); document.write( "Now go back and plug in x to find FBE.
\n" ); document.write( "If they're complementary,
\n" ); document.write( " $\"10x%2B52=90\"$
\n" ); document.write( " $\"10x=38\"$
\n" ); document.write( " $\"x=38%2F10\"$
\n" ); document.write( " $\"x=19%2F5\"$
\n" ); document.write( "Similarly go back and plug in x to find FBE. \n" ); document.write( "
