Which lines are perpendicular to the line y - 1 = 1 (x+2)? check all that apply
y + 2 = -3(x – 4)
y - 5 = 3(x + 11). y=-3x - 5 / 5
y = 1x-2
3x + y = 7

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
