I'm trying to find the best solution for solving a problem in which I must form an operation with three vectors in polar form, ending with a sum in rectangular form. The operation is as follows:

(5 [itex]\angle[/itex] 0°) + (20 [itex]\angle[/itex] -90°) - (6 [itex]\angle[/itex]180°) =

2. Relevant equations

Z_{1}[itex]\angleθ[/itex] + Z_{2}[itex]\angleθ[/itex] = (Z_{1}+ Z_{2}) [itex]\angleθ[/itex], (X_{1}+ jY_{1}) + (X_{2}+ jY_{2}) = (X_{1}+ X_{2}) + j(Y_{1}+ Y_{2})

3. The attempt at a solution

I tried using the Triangle Law R= (a+b)+(b+c). I'm not sure if I did this correctly or not, but I ended up with this vector in rectangular form: -9 + j1.1*10^{-15}

I'm posting to verify if I did this correctly or if I missed anything.
