Make a right triangle with leg of 30ft and opposite angle of 12.7deg\r
\n" ); document.write( "\n" ); document.write( "Solve for other leg
\n" ); document.write( "\"tan%2812.7%29=%2830%2Fa%29\"
\n" ); document.write( "\"a=%2830%2Ftan%2812.7%29%29\"
\n" ); document.write( "\"a=133.12049850724641310871629550339=133ft+1in\"\r
\n" ); document.write( "\n" ); document.write( "Repeat with new angle of 14.5deg
\n" ); document.write( "\"tan%2814.5%29=%2830%2Fa%29\"
\n" ); document.write( "\"a=%2830%2Ftan%2814.5%29%29\"
\n" ); document.write( "\"a=116.0013928469621446992171095257=116ft+0in\"\r
\n" ); document.write( "\n" ); document.write( "Subtract
\n" ); document.write( "\"a%5B1%5D-a%5B2%5D=d\"
\n" ); document.write( "\"133-116=d\"
