Raúl is pouring a concrete walkway in his backyard. he decides to put a turn of 30° from the horizontal in the walkway to go around a tree and flowerbed. once the walkway is past the tree, raúl wants to continue the walkway in the same direction as before. at what angle should he put the second turn so that the walkway will continue in the same direction as before it reached the flowerbed? why?
a. 150°. the new angle is a same side consecutive angle of the original angle. since the original and final paths are parallel, the two angles must be supplementary.
b. 150°. the new angle is on a straight line with the original angle, so the two angles must be supplementary.
c. 30°. the new angle is an alternate interior angle of the original angle. since the original and final paths are parallel, the new angle must be congruent to the original angle.
d. 30°. the new angle is a corresponding angle of the original angle. since the original and final paths are parallel, the new angle must be congruent to the original angle.
