B)y1 is 12 units lower than y2.
C)y1 is 12 units to the left of y1.
D)y1 and y2 are reflections in the x-axis.

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
