First find the components in the horizontal and vertical directions.

 

Horizontal:  Fx = 9 - 14*cos(65°)    or  Fx = 3.083   

 

Vertical:   Fy = 14*sin(65°)  or Fy = 12.688

 

The resultant has magnitude sqrt(Fx2 + Fy2)  = 13.058

 

It has an angle to the horizontal axis of  tan-1(Fy/Fx)  =  76.34°  

 

resultant
