Steve has given you the answer, but in case you can't wait for him to
finish work you need to enter your formula as:

=301.5/COS(RADIANS(19.79))

19.79 are degrees, and as trigonometrical functions in Excel use
radians you have to convert these as shown.

Hope this helps.

So there must be another solution to this problem. If you do this on a
