Dear Student,
Please find the following solution,
 
Summation of forces in x direction= 20 + 30 cos 30 + 40 Cos 60 - 60 Cos 60 = 35.98
Animation of forces in wind direction is equal to 30 sin 30 + 40 sin 60 + 50 + 60 sin 60= 151.60
Resultant of a force acting is
R=√(fx)*(fx)+(fy)*(fy)
R=155.80
Alpha =tan(inverse(fy/fx))
Alpha=76.64
 
 
Hope this helps you
