---------------------------------------------------------------------------------------------------------------------------

OK......first, let's subtract 3341 from each side   This gives

-3280 = -2900cosX

Divide both sides by -2900   We have

1.131 = cosX

Do you see the problem here??

The cosine function only returns values between -1 and 1, inclusive.

Thus, this problem has no solution !!
