$- 2.9 + 0.75 i$ $-2.9+0.75i$

Explanation:

$evaluate cos and sin and multiply result by 3$ $"evaluate cos and sin and multiply result by 3"$

$= 3 (- 0.968 + i 0.25)$ $=3(-0.968+i0.25)$

$= - 2.9 + 0.75 i \leftarrow in standard form$ $=-2.9+0.75ilarrcolor(blue)"in standard form"$

Standard form: $- 2.90 + 0.75 i$ $-2.90+0.75i$

Explanation:

Trigonometric form: $3 (cos 165.5 + i sin 165.5)$ $3(cos165.5+isin165.5)$

Standard form: $3 (0.967 + i \cdot 0.254) \approx (- 2.90 + 0.75 i) (2 d p)$ $3(0.967+i*0.254)~~ (-2.90+0.75i) (2dp)$

Standard form: $- 2.90 + 0.75 i$ $-2.90+0.75i$ [Ans]
