I= sq root (Ir^2+Ic^2) so I= sq root (0.785^2 + 4.508^2) =4.57mA

Not clear.

I=0+Ir+(11+(11)+(0+Ic)) where 11 is a number You can take any number in that place.

Current across the capctor leads the current across the resistor by 90 in phase diagram. so,total current=sqrt(sq(Icapactor)+sq(Iresistor)).

We know that V=IZ where z=R//X where X=1/2PIfc.

Current in parallel form added.

Why square rooting the value?

Why square rooting Ir & Ic?

Ir and Ic are not in phase (90 degrees out of phase). In a graphical analysis, they will form a right triangle, the longest side (hypotenuse) is the total current (geometric sum), which can be solved by using the Pythagorean theorem. It=sqrt(Ir^2 + Ic^2).
