Let $\"+a+\"$ = the rise of the slope
\n" ); document.write( "Let $\"+b+\"$ = the run of the slope
\n" ); document.write( " $\"+a%2Fb+=+.427+\"$
\n" ); document.write( "Let $\"+theta+\"$ = the angle the mountain
\n" ); document.write( "makes with the horizontal
\n" ); document.write( "---------------------------------
\n" ); document.write( " $\"+tan%28+theta+%29+=+.427+\"$
\n" ); document.write( " $\"+theta+=+23.122+\"$
\n" ); document.write( "-----------------------
\n" ); document.write( "The angle to the nearest degree is 23 degrees
\n" ); document.write( " \n" ); document.write( "
