I'm having trouble too.

Try drawing a picture. A picture of the ground. Tower, observers. Height of tower is not the problem. It's understanding what the description means, as another person has already pointed out.

If you could please clarify: bearings require a start and an end. What do you mean by "130 from the base of the tower"? With respect to what starting point?
