\n" ); document.write( "Draw the picture.
\n" ); document.write( "----
\n" ); document.write( "Label to base as 5 miles.
\n" ); document.write( "The side opposite the 55 degree angle is \"h\":
\n" ); document.write( "----\r
\n" ); document.write( "\n" ); document.write( "tan(55) = h/5 miles
\n" ); document.write( "----
\n" ); document.write( "h = (5 miles)*tan(55)
\n" ); document.write( "---
\n" ); document.write( "h = 5*1.4281..
\n" ); document.write( "h = 7.1407 miles
\n" ); document.write( "OR
\n" ); document.write( "height = 7.1407*5280 ft = 37,703 ft
