Rachel is a lunchroom supervisor at west school the children eat lunch at 15 long tables. when all tables used 240 children can eat at one time how many seats are there at each table

no

step-by-step explanation:

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
