Help! Use the identity of i^2=-1 to compute the powers of i and complete the table

Step-by-step explanation:

i^3= -i

i^4= 1

i^5= i

i^6= -1

i^7=  -i

For the other questions, can you give me the value of N. If that is not possible, then sorry I can not help you. And feel free to report this if this is not useful :(

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
