If you draw this with the taller building on the right, there is a right triangle with leg 60 m and an angle of 40 degrees.
\n" ); document.write( "Tan 40=x/60, and x is the difference in height between the buildings.
\n" ); document.write( "x=60 tan 40=50.35
\n" ); document.write( "Subtract that from 90 and the other building is 39.65 m high.
\n" ); document.write( "
\n" );
