Question

Please help! All the help means the world to me!

Answer 1

First, we know that there are 5 poles. Next, we know that the equation
`(n(n-1))/(2)` represents the amount of strings needed if we have n number of poles. Therefore, we can plug 5 poles into n (as n represents the amount of poles) to get
`(5(5-1))/(2)` =
`(5*4)/(2)` = 10 as our answer.
