Question

Raul is laying a cement 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 he gets past the tree, he 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 he came to the flowerbed?

Answer 1

Not sure how he can turn from the horizontal, unless he goes uphill, but whatever the direction, just turning 30° in the opposite manner will put him on a course parallel to his original one.

Answer 2
