Answer:
12.43 - 3.8i
Step-by-step explanation:
The standard form of a complex number is a + bi
In this case, the number is
13(cos(343) + isin(343))
Multiplying 13 by both expressions inside the parenthesis, we get
13cos(343) + i(13)(sin343)
13(0.95) + i(13)(-0.29)
12.43 + (-3.8)i
Therefore, the standard form of the number is
12.43 - 3.8i
