Statics 2.93 - How to determine magnitude and direction of the resultant acting on the flag pole

Question: If F_b = 560 N and F_c = 700 N, determine the magnitude and coordinate angles of the resultant force acting on the flag pole.

Thank you guys for watching.

Please let me know if you have any comments or suggestions and also if you have any other problem you would like to go over with.

Hi, i have a question in regards to the directional angle calculation.
Ive been having difficulties understanding the calculation. You said alpha is = cos-1 (460/1175) which gave you 67

Then Beta = cos-1 (-40/1175) which you got 92.

When i did my calculation i got something entirely different so could you kindly explain the calculations you did in that part please?

Thank you.
It’ll mean a lot if you do.
