By your question I assume that you actually mean what are the solutions for x?
One solution is x = 60, which should be obvious.
Then draw a sin graph and find the other point in this range where it is at the same height.

There's more than 1 value because of the range
Yes, but a calculator would only give you one answer.
If you don't fancy the graph method then draw a CAST diagram.

Yes, that is the point of the question ... All your suggestion does is give the original 60 ... It was a pointless suggestion
