|Its very simple
Since j is in denominator it will lag by angle=-90degree

|Current lead in capacitor by 90 so impedance will become -90.|
|Amit said: (Mar 10, 2014)|
|Why it is -90 it should be +90?|
|Arslan Zahoor said: (Jan 19, 2015)|
|Current is leading to voltage 90 degree in capacitor and current is lagging to voltage 90 degree in inductor.|

|Z = R-jxc as R which is not given, it's negligible
Z = -j150.
r = √ (x^2+y^2),
r = √ (+(-150)^2),
r = 150,
∠= tangent inverse(y/x),
= 90 = -90 and sign - because in capacitive impedance lags by 90.
