What is the 100th term of the sequence with a1 = 222 and d = -5? A) -278
B) -273
C) 722
D) 717

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

idk what the heck he answer is, i’m just putting this here so i finish my account
