Answer:
B because the 3 interior angles of any triangle adds up to 180 degrees.
Step-by-step explanation:
-2 + n = -8(1 - 8n) + 6
Distribute the -8
-2 + n = -8 + 64n + 6
Combine like terms.
-2 + n = 64n - 2
Add 2 to both sides and subtract n from both sides.
0 = 63n
Divide both sides by 63
0 = n

Exercise 1:
The easiest way to compute powers of complex numbers is to write them in the form

In this form, you have

The magnitude of the number is given by

So, we have

As for the angle, we have

So, we have

Finally,

Exercise 2:
You simply have to compute the trigonometric function:

So, we have
