AAMC #3 , Question 15

[conquerDat]

For this question, how would we know what arc tan 0.75 is?

Also since it is in translational equilibrium I started to split the diagonal force vector into its components , F cos 0 and F sin 0 inorder to balance the 4N on the left and the 3N down

Is that approach feasible?

Thank you for the help everyone!

1) trigonometry.. you should be able to know the common angles and such

2) if you post the question/picture, I can probably help
