document.write( "Let d be the distance from the building to the monument, horizontally.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then equation you need to solve is  d*tan(13°) + d*tan(8°) = 70 feet.\r\n" );

document.write( "\r\n" );
document.write( "From the equation,  d = \"70%2F%28tan%2813%5Eo%29+%2B+tan%288%5Eo%29%29\" = \"70%2F%280.231+%2B+0.141%29\" = 188.17 ft.    ANSWER\r\n" );
