Question

Help help please man im struggling

Answer 1

- 9.539 + 15.265i

Explanation:

express the complex number in trigonometric form, that is

`z_(1)` = |
`z_(1)` |(cosΘ + isinΘ)

= 18(cos122° + isin122°)

= - 9.539 + 15.265i

Answer 2

z = -9.538546756+ 15.26486573i

Explanation:

z = |z| cos theta + |z| i sin theta

We know |z| and theta

z = 18 cos 122 +18i sin 122

z = -9.538546756+ 15.26486573i
