Grade 12General Physics

Two forces of 60N and 80N acting at an angle of 60degrees with eath other. Pull an object. What single pull will replace the given forces. What is the direction of the force. The answer is 121.7N which is ok.
But the direction is given 34.7degrees.i am getting 25.28.
The angle is tan theta=80sin60/60+80cos60 or 60sin60/80+60cos60. I feel it is the latter. But in my book it is80sin60/...... Pls help me.
Thanks and regards,
Jai
