The formula Hitchman is using computes the tension on one of the suspension ropes (which makes sense when you're interested in the threat of one of these ropes breaking.) After much weeping and gnashing of teeth it was established that that formula is

tension = (W/2)/sin(angle)

where W is the weight. You can punch this up on any calculator. With W = 200 lbs and angle = 45 degrees you get tension = 141.4 lbs.
