Do you know the condition of the static state??
i misunderstood that question. do you know how to decompose the vector??
i will attach file.
Strange geometry! You have to resolve the vectors (using the dimensions provided) then add up their components.
i tried to attach file. but my phone camera has a problem. so i will just note you that first add two tension in vector interpetation and find angle between two vector than you can find answer (use parallelogram)
