I understand all the concepts, the only thing I don't know is were does Yc=hc/sin 60 comes from.
Im kind of visual, if you could upload how you do it, it would help

Where is Yc? Is it the hypoteneuse of the triangle with hc?

Can someone explain why do I need to divide the two shears?(last step)

Is ratio calculated just by dividing two things?
