Answer:
Step-by-step explanation:
The first term is 22. It looks like each term after that is the term before, plus a negative 3.
a-sub-one = 22
common difference = d= -3
Formula for 
:
= 25 - 3n
A △ Has to have 180º so 72+56 b would have to be appx. 52degrres
So since they are similar
AC/BC=CD/CE
so
(66-x)/30=(x+4)/5
times both sides by 5
(66-x)/6=x+4
times both sides by 6
66-x=6(x+4)
distribute
66-x=6x+24
add x to both sides
66=7x+24
minus 24 from both sides
42=7x
divide both sides by 7
6=x
x=6 units

im sorry i don't know the answer i just need to do this so that i can ask my question pls forgive me
V=(4/3)pir^3
