Answer:
1+i
Step-by-step explanation:
To find the 8th roots of unity, you have to find the trigonometric form of unity.
1. Since then
and
This gives you
Thus,
2. The 8th roots can be calculated using following formula:
Now
at k=0,
at k=1,
at k=2,
at k=3,
at k=4,
at k=5,
at k=6,
at k=7,
The 8th roots are
Option C is icncorrect.
Answer:
horizontal - 5 units long
verticle sides - 1 unit tall
perimeter - 12 units
Step-by-step explanation:
2k - 4 = 2 + k
(Subtract both sides by k)
k - 4 = 2
(Add both sides by 4)
k = 6

Answer:
b=14
Step-by-step explanation:
the two labeled angles are vertical angles. according to the vertical angles theorem, they must be equivalent. therefore, we can set them equal to each other and solve.
5b=b+56
4b=56
b=14
