Just keeping in mind the tangent graph and its relation in this circuit: (When Calculator is not allowed).
tan(angle)=2*π*f*L/R; .
For this question we can use the act==> angle is less than 45 if 0<(2*π*f*L/R)<1.
Otherwise greater than that in positive values. Here we have (2*π*f*L/R) <1. Also, note that (2*π*f*L/R) will be positive always.

XL = 2*(3.14)*f*L
=2*3.14*5*10^3*24*10^-3
=240(3.14)
Total phase angle= tan inverse(XL/ R)
= tan inverse(240*(3.14)/10^3)
=37.015
=2*3.14*5*10^3*24*10^-3
=240(3.14)
Total phase angle= tan inverse(XL/ R)
= tan inverse(240*(3.14)/10^3)
=37.015

I studied phase shift is tan inverse of (imaginary part/real part). Why that formula applied here?

tan (q) = XL/R
q = Phase Angle (deg)
XL = Inductance Reactance(ohm)
R = Resistance (ohm)
q = Phase Angle (deg)
XL = Inductance Reactance(ohm)
R = Resistance (ohm)

Phase angle=tan^-1(wL/R)
=tan^-1(2*3.14*24*10^-3/1*10^-3)
=37
=tan^-1(2*3.14*24*10^-3/1*10^-3)
=37

How to calculate inverse values? We do not have calculator in the exam halls right.

Phase angle
= cos inverse((1k)^2/((1k^2)+(2*3.142*5k*0.024)^2)^0.5
= 37.015
= cos inverse((1k)^2/((1k^2)+(2*3.142*5k*0.024)^2)^0.5
= 37.015

Phase angle = tan^-1(wL/R).
= tan^-1(2*3.14*5*10^3*24*10^-3/1*10^3).
= 37.
= tan^-1(2*3.14*5*10^3*24*10^-3/1*10^3).
= 37.
