Hello, I got this problem from a book
"A light ladder leans against a perfetly smooth vertical wall at an angle of 30 degrees to the horizontal. A load of 800N is placed 3-quarters of the way up the ladder. If the ladder rests on a rough horizontal surface which prevents slipping, find the magnitude and direction of the reaction between the ladder and the ground"
Since the system is in equilibrium, I resolved vertically and got
R sin(theta) = 800
where R is the reaction force, and theta is the angle of the reaction force with the horizontal.
The problem is I can't get another equation so that I can find R and theta.
Any help is appreciated, thanks!
