A tightrope walker stands at position shown below. The Tension in the cable on the right is 1800 N, find the walker's mass.
The angle on the right is 70º and the one on the left is 80º.
The Attempt at a Solution
So I presume you have to draw a vector diagram, but I am totally unsure of how to do that for this situation. Once the vector diagram is drawn I assume that you use the sin law to figure out the other angle. And then from the force of gravity derive the weight. I just need some help getting started, and then I should be able to do it on my own.
