Answer: (-3m, -4m)
Explanation:
First find the components of the vector.
Before doing that you must know the following values:
cos 37° = 4/5
sin 37° = 3/5
Along x-axis: 10 cos 37° = 8
Along y-axis: 10 sin 37° = 6
Now,
Terminal Coordinates: ((5-8), (2-6))
Terminal Coordinates: (-3m, -4m)
Hope this helps
