Question

Consider two vectors F~1 with magnitude 69 N inclined at 177◦ and F~2 with magnitude 58 N inclined at 286◦, measured from the positive x axis with counterclockwise positive.
What is the magnitude of the resultant vector F~1 + F~2 ? Draw the vectors to scale on a graph to determine the answer.
1. 108 N
2. 127 N
3. 172 N
4. 111 N
5. 74 N
6. 93 N
maybe number 4
