Direction and Magnitude

[Itel]

Can someone please help me with this? I really appreciate any help you can provide.

Two forces with magnitudes of 200 and 100 pounds act on an object at angles of 60° and 170° respectively. Find the direction and magnitude of these forces. Round to two decimal places in all intermediate steps and in your final answer.

Use the definition of resultant force:

\(\displaystyle \vec {R} \ = \ \sum {\vec {F}}\)

To add vectors you may choose to use law of parallelogram or decompose the vectors into orthogonal components (cartesian) and add.

" Find the direction and magnitude of these forces"??? Surely, that's not what the problem asks! You are GIVEN those! Doesn't it ask for the direction and magnitude of the resultant force?
