Having a little problem understanding why this example converted polar to rectangular form to get Z. What is wrong with just leaving it in polar form and doing the algebra to get the value for Z

Best Answer
It's semantics. If someone asked for an answer as impedance then I would tend to expect to see this answer in polar form. Converting to rectangular along the way is the simplest way of analysing the problem and converting back to polar at the end gives the answer as how I would expect it to be: -
