Question 1168649
F1 = 7200 N straight up
F2 = 5300 N at 34 deg
To resultant force R = sqrt(Fx^2 + Fy^2), where Fx and Fy are the net forces 
in the x and y directions.
Since one crane pulls straight up, the x force has one component:
Fx = F2*cos(34)
The y force has two components:
Fy = 7200 + F2*sin(34)
The angle the pillar moves is in the direction of the applied force:
A = arctan(Fy/Fx)
