We have the formula
\n" ); document.write( " $\"%28L+%2F+2pir%29+=+d%2F360\"$
\n" ); document.write( "First, we need to convert to same units, so, 1 2/3 ft = 18 in.
\n" ); document.write( "Using substitution, we get
\n" ); document.write( " $\"%2818+%2F+%282pi%2A45%29%29+=+d%2F360\"$
\n" ); document.write( "cross multiplying, we get
\n" ); document.write( " $\"18%2A360+=+d%282pi%2A45%29\"$
\n" ); document.write( " $\"76%2Fpi+=+d\"$
\n" ); document.write( "which is d ~ 24.192 degrees. \n" ); document.write( "

\n" );
