Tina collects stuffed animals. she has 8 teddy bears, 9 dogs, 10 frogs, and 6 monkeys. what is the ratio of monkeys to teddy bears?

3x^3-x^2+6x-9

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
