Answer:
( cos40° + isin40°)
Step-by-step explanation:
To divide

=
[ cos(x₁ - x₂) + isin(x₁ - x₂)
Given

=
( cos(90 - 50)° + isin(90 - 50)°
=
( cos40° + isin40° )
Answer:
No
Step-by-step explanation:
multiply each side of 6:1 by 3 to get it equivalent. 18:3 is not equal to 12:3 so no
Answer:
I believe it's 12
