Katie and her sister have entirely different features and traits. Katie has blond hair and brown eyes, but her sister has red hair and blue eyes. The sisters have different traits, but their differences are not caused by mutations. Mutations in living things are caused by various factors. Which three facts can cause mutations?

first one because it can't have a fraction in it

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

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
