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
Answer from: Quest
step-by-step explanation:
at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
