You can put this solution on YOUR website!
If t is the height of the tower, then t-279 is the height of the antenna. So:
\n" ); document.write( "t+t-279=1729
\n" ); document.write( "2t= 2008
\n" ); document.write( "t=1004
\n" ); document.write( "The tower is 1004 ft. Then antenna is 725 ft. high. ☺☺☺☺
