It's getting cold outside! The temperature dropped steadily at a rate of about 4 degrees every hour. If
the temperature dropped a total of 22 degrees,
how many hours have passed? Let h represent the
number of hours

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
