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

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

=
( cos(90 - 50)° + isin(90 - 50)°
=
( cos40° + isin40° )
Y=1 because if you remove the y’s, you see 1.4+0.09=1.49

Answer:
Step-by-step explanation:
The equation
2 = (1/6)x represents this situation.
2 is 1/6 of some value. In this case, the value is the total number of marbles. 2 represents 1/6 of the total number of marbles is how to read that equation in context. Solve that equation for x
2 = (1/6)x
12 = x (multiply both sides by 6 to get rid of the fraction)
