Find the 12th term of the arithmetic sequence whose common difference is d=9 and whose first term is av1 = 1. PLEASE HELP ME
the "v" is ^ but upside down I don't know how to put it pointing down.

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

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
