Solving this partial fraction - phasors

[katta002]

I'm having some difficulty Solving this partial fraction:

(3.84e7)/(s(s^2+6.4e4s+1.6e9))= (3.84e7)/(s(s-3.2e4+j2.4e4)(s-3.2e4-j2.4e4)

how do u find the angle?
I know the equation but I don't know how to find the B with it conjugate.
eq: 2B/_theta

but I don't know how to find theta and the B. Please can u help me
