Hi, I have a, I believe simple, problem. I am studying for a Statics final and while doing problems with a Truss I came to a problem that I did not know how to solve. It is already solved for me, but I do not get how. The truss has a force coming out from the side but instead of an angle there is a right triangle. I do not understand how to use the triangle. I will upload a picture of the problem and the answer. If anyone can help me understand how the triangle is being used to compute the problem I would greatly appreciate it! Thanks in advance!!!(adsbygoogle = window.adsbygoogle || []).push({});

For example I do not understand where or why they get (4/5)Tcd or 130(12/13)
