Answer:

- 9.539 + 15.265i

Step-by-step explanation:

express the complex number in trigonometric form, that is

z_{1} = | z_{1} |(cosΘ + isinΘ)

                       = 18(cos122° + isin122°)

                       = - 9.539 + 15.265i

Hey there,
7 / 10 + 1 / 6 
1st Step : Make the denominators the same (30)
7 / 10 (multiply by 3) = 21 / 30
1 / 6 (Multiply by 5) = 5 / 30
Step 2: Add them together.
21 / 30 + 5 / 30 = 26 / 30
