Question

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?

Answer 1

Step-by-step explanation: Raúl should put a turn of -30° in the walkway after the tree in order to continue in the same direction as before. This is because the negative angle will cancel out the positive angle and the walkway will continue in the same direction as before.
