Step-by-step explanation:
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:
3.50x+6.50=y
Step-by-step explanation:
Answer:
h=v/πr²
Step-by-step explanation:
v=πr²h
v/π=r²h
v/πr²=h
