1.41666666667 is the answer
Answer:
-10/3 is the answer
Step-by-step explanation:
Given are two complex numbers as

Recall Demoivre theorem as
(cosA+isinA)(cos A+isin B) = cos(A+B)+isin(A+B)
Hence here we have sum of angles as
A+B = 63+117 =180

=
Since sin180=0 and cos 180=-1
Answer:
The correct answer is B
Step-by-step explanation:
Kinda complicated to explain, if you need me to then comment and I'll do it
Answer:
