Im asked to find the total impedance. So far Ive been able to find the impedance of all the individual components.

How do I proceed from here and get the answer in the correct form?

The answer should be:

You have the answer in "rectangular" form. This means you have a complex number with a real term and an imaginary term.

The solution is given in "polar" form which means that you need magnitude and a direction. Google "rectangular to polar conversion" and you should find what you're looking for.

Nevermind, I forgot to change back from radians to degrees. Thats why I didnt get the correct angle.
Units are critically important. So even though angular measure in radians is technically dimensionless, it is a very good idea to explicitly write "rad" as the unit when you are using radians so that you have a smoking gun screaming at you that the two values are not using the same units.
