firstly , draw the path 2.3 to east and 4.1 to the north. you’ll get a right - angle triangle . the hypotenuse is the displacement.
to find the distance , use Pythagoras theorem.
let the displacement = c
c ^ 2 = 2.3 ^ 2 + 4.1 ^ 2
c = 4.7 km
then , you need to find the angle.
tan theta = 4.1 / 2.3
theta = 61 degree
i am sorry if my answer was wrong but i hope it helps you and you can understand it : )
