V of inductor directly proportional to the reactance of inductor when V across L greater than V across R. Xl is greater than R circuit in inductive in nature. So phase angle increases.

COS(phaseangle) = R/Z.
V = IZ.
If V of inductor increases, Z increases so cos(phaseangle) decreases so phase angle increases.
V = IZ.
If V of inductor increases, Z increases so cos(phaseangle) decreases so phase angle increases.

Vr<Vl.
IR<IXL.
R<Xl.
Cos φ= R/Z.
IR<IXL.
R<Xl.
Cos φ= R/Z.

It is explained by the phasor diagram.
