```							lets considerN1=normal force from the wall to the ladderN2=normal force from the ground to the ladderlet friction force due to the ground f pass through the contact point at the groundA=angle made by ladder with wallsinA=3/root(13)balancing forces-N2*6=500*4/3     (here 4/3 m is the normal distance of the ground contact point to the line of weight action force)N2=111.11 N
