Coil and resistor in parallel -- How to calculate the phase angle?

[MisterP]

Hello. So I have a coil and a resistor in parallel connection. It is powered by alternating current. I have to calculate angle between voltage and current, what is the formula? I know the reactive resistance in coil, I know resistance of resistor, voltage across both of them and amps flowing through them as well.

You can do it using phasor algebra or by drawing the phasor diagram. What values are given? What have you tried?

I know that there is a formula for calculation, but I cannot find it.
Voltage across both of them is 100V, amps through R is 0.55A and amps on XL is 1A. There is an ampmeter before both of them as well and it shows 1.18A

If the inductor is ideal, this can't be true (and this information is not required as well). Please post the complete question with given parameter values and details.
