Angles are supplementary.
\n" ); document.write( "s + r = 180
\n" ); document.write( "s = (180-r)
\n" ); document.write( " The measure of angle s is 7 degrees less than one-fourth of the measurement of r.
\n" ); document.write( "s = \"1%2F4\"r - 7
\n" ); document.write( "Replace s, write 1/4 as a decimal
\n" ); document.write( "180 - r = .25r - 7
\n" ); document.write( "180 + 7 = .25r + r
\n" ); document.write( "187 = 1.25r
\n" ); document.write( "r = 187/1.25
\n" ); document.write( "r = 149.6 degrees
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this
\n" ); document.write( "s = 180 - 149.6 = 30.4 degrees
\n" ); document.write( "see if this is true
\n" ); document.write( "\"The measure of angle s is 7 degrees less than one-fourth of the measurement of r.\"
\n" ); document.write( "30.4 = .25(149.6) - 7
\n" ); document.write( "30.4 = 37.4 - 7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
