Explanation / Answer

part a)

displacement from the starting point = sqrt(15.5^2 + 23^2)

displacement from the starting point = 27.7 m

part b)

Now, for the angle of displacement

angle of displacement = arctan(A/B)

angle of displacement = arctan(15.5/23)

angle of displacement = 34 degree

the angle of displacement is 34 degree
