trig formula

[nvious62]

hello all i have tried searching and can't figure this out. what i am doing is getting a resultant of force vectors. i can get the resultant but on the angle i am having trouble. what i put in is =DEGREES(ATAN2(F24,B24)) and it is good it will give me the degrees from the positive x axis up to 180 fine. where I'm having problems is when i go past that 180 then it will start counting down -179.9. i need it to be positive all the way to 360. The professor wants the angles measured from the positive x axis and depending on what the degrees are to give a message to what quadrant it is in. any help is greatly appreciated.

=if(degrees(atan2(f24,b24))<0,degrees(atan2(f24,b24))+360,degrees(atan2(f24,b24)))
