you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

the answer is 99.

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

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
