Two forces are applied to a car in an effort to accelerate it.

Please let me know how to actually figure out this answer since I am doing it incorrectly. I dont need the solution but I need to know what to do...

A car is driving straight up.
The first force is 10 degrees to the West of the vertical line that goes through this car. (450N)
The second force is 30 degrees to the East of this vertical line (380N)

What si the resultant of these two forces?
