Question

A ladder rests against a wall making an angle with horizontal. The foot of the ladder is pulled away from the wall through a distance a' so that it slides a distance b' down the wall making an angle with the horizontal then value of a/b is

Answer 1

A ladder rests against a vertical wall at an inclination a 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 b to the ground . Show that Cos a minus cos b by sin a minus sin b equal to p /q

A ladder rests against a wall at an angle α to the horizontal. Its foot is pulled away from the wall through a distance a, so that it slides down a distance b down the wall making an angle β with the horizontal. Show that

a/b = cosα - cos β / sin β - sinα

( Its the same question you have asked. I have only taken 'a' instead of 'p' and 'b' instead of 'q'.)
