a ladder rests against a vertical wall at an inclination of alpha to the horizontal.its foot is pulled away from the wall through a distance p so that its upper end slides a distance q down the wall and then the ladder makes an angle of beta to the horizontal show that
p/q= cos beta - cos alpha/ sin alpha -sin beta
how to solve this to get 200/root 3?
x(root 3+1)=200(root 3+1/root 3)
