I have the solution for the problem. I just don't understand HOW this formula was derived. It came from another student, and nowhere in the text has our teacher taught us how do something like this..

What is the force exerted by the string on the wall at point A in the figure if the suspended fish has mass m = 0.56 kg?

m * g * (Square root of 3)

.56 * 9.81 * (square root of 3) = 9.52 N .. but why would you use the square root of 3 here? 30 degrees?
