hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

30 people weigh 160 pounds or more

1 and 0

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
