Given:
You know that:
In order to solve the operation, you can follow these steps:
1. Distribute the negative signs. Remember the Sign Rules for Multiplication:
Then:
2. Combine the like terms (add the Real Parts and add the Imaginary Parts):
Hence, the answer is: Option B.
Answer:
∠B ≈ 56.25°
Step-by-step explanation:
Since the triangle is right use the cosine ratio to solve for B
cosB = =
=
, thus
B = (
) ≈ 56.25°
