If it comes in exam, then we can do it diagrammaticallyâ€¦since AC=5 units and radius of incircle is 1 unitâ€¦hence drawing tangents .we can take it to be right angle triangle.

But correct method I donâ€™t know.

I think this is the only methodâ€¦

If we go through formula then it will be very lenghty.

Yes there is a shortcut method.There will be certain constructions and one angle has to be taken as theta.then we have to solve I donâ€™t know about this method correctly but it works.
