A ladder rest against a wall making an angle alpha with the horizontal. The foot of the ladder is pulled away from the wall through a distance x , so that it slides a distance y down the wall making an angle beta with the horizontal. Prove that x=ytan(alpha+beta)/2dot

A ladder rests against a wall making an angle alpha with the horizontal. The foot of the ladder is pulled away from the wall through a distance x, so that it slids a distance y down the wall making an angle beta with the horizontal. Then prove that x = y tan ((alpha + beta)/(2)) .

A ladder leaning against a vertical wall is inclined at an angle alpha to the horizontal. On moving its foot 2m away from the wall, the ladder is now inclined at an angle beta . Find the vertical distance moved by the ladder.

In the road of Laxmi's locality there is a ladder of 15m length kept in such a way that it has touched Pujas's window at a height of 9 m above the ground. Now keeping the foot of the ladder at the same point of that road, the ladder is rotated in such a way that it touched Laxmi's window situated on the other side of the road. If Laxmi's window is 12m above the ground, then determine the breadth of that road.
