Expert Answer
Let the length of the ladder be l
Let the height upto the ladder's top end from ground be h
Let the distance between the wall and the foot of the ladder be p
Then according to the question,
sinx=h/l, cosx=p/l
siny=(h-b)/ l ,cosy=(p+a) / l
So, we get, h-(l siny) =b
and (l cosy) - p= a
now you can find a/b using above equations for values of h and p.
