natta225 [31]
Cos θ=1/3
cos θ=sen (90-θ)
therfore:
sen (90-θ)=1/3

To chek
θ=arc cos 1/3=70.53º

Help I don’t know what to do
Allushta [10]
Symbol i we call imaginary unit =>
 
This is basic

i^2= i * i = -1
i^3= i^2 * i = -1 * i = - i
i^4= i^3 * i = -i * i = - (i * i )=- (i^2)= - (-1) = 1
i^5= i^4 * i = 1 * i = i
i^6= i^5 * i = i * i = i^2 = -1
i^7= i^6 * i = -1 * i = - i
i^8= i^7 * i = -i * i = -(i * i)= -( i^2)= - (-1) = 1

You have all you need.
You conclude which simplifications of the power i are correct.

Good luck!!!!

Answer:

a=5

Step-by-step explanation:

2. Subtract 16 from 136.

You'll get 120.

3. Divide 120 by 24 to get <em>a</em> by itself.
