Answer:
c = 13.5 m
Explanation:
from the attached diagram, we can apply the cosine rule to get the resultant displacement (c) where
c = 
- from the diagram β = 55 degrees because they are alternate angles
θ + β = 180 (sum of angles on a straight line )
θ + 55 = 180
θ = 180 - 55
θ = 125 degrees
- c =

c = 
c =
c = 13.5 m
