Happy New Year from MrBillDoesMath!

Answer:

 i ^ (2n) = (i^2)^n = (-1)^n = -1 if n is odd and = 1 if n is even

 i ^ (2n+1) = i^(2n)* i =     -1 * i = -i if n is odd and =  1*i = i if n is even


Not sure if this answers your question but hopefully pushes you n the right direction.


Thank you,

Two Parnell lines (lines, L, and L2) are intersected by a transversal (L,3). Fill in the missing angle measure for each diagram
almond37 [142]

Apply the : congruent (corresponding alternate exterior and alternate interior angles) and supplementary (consecutive interior angles) theorems

step-by-step explanation:

The property to apply here is : congruent (corresponding alternate exterior and alternate interior angles) and supplementary (consecutive interior angles)

1.h = 180°-120°=60°=e=d=a

  f=120° = c=b

2.b=180°-105°=75°=c=f=g

   a=105°=e=h

3. f=180°-36°=144°=g=c=b

   a=36°=d=h

4. a=180°-161°=19°=e=h=d

   c=161°=f=g

5. f=180°-145°=35°=g=c=b

   a=145°=d=h

6. b=180°-25°=155°=c=f=g

    25°=d=e=h
