I solve these two equations and I got x=51.65degree but in my book x=128.35

so Iam confused

the equations are:

54.684=F Cos x...........(1)

69.313=F Sin x.............(2)

Results 1 to 6 of 6

## Re: Im I right??

So your equations are F cos(x)= -54.684 and F sin(x)= 69.313?

Then clearly 51.65 degrees cannot be correct. I presume neglecting the negative was your error in doing the calculation and you see now that

128.35 degrees is correct? (Actually, I get 128.27 degrees.)
