how to calculate apparent power | How to find angle between voltage and current

we are going to see about apparent power calculation and finding angle between v and I without using scientific calculator.
Formula for apparent power = V*I
Formula for real power = V*I*Cos ∅
Formula for reactive power = V*I*Sin∅
apparent power (S)= real power(P) + j reactive power(Q)
you can easily find the value of angle between V and I without using Calculator.

Good and useful brother but need more clarity for power factor calculation as well lagging and leading
