Ok - So 2 ends of a cord of length 5.6m are attached to a beam 4.8m apart. A shoe is hanging off the cord 2.1m from one end.

When i'm calculating the angles that are the 2 sections of cord meet the beam, is this correct...

Using the cosine rule, we can asign a = 5.6, b = 4.8, c = 2.1

So...

So

I'd then do the same to find the other angle?

If not please could someone advise
