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 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. THEN x=

A ladder rests against a wall at an angle alpha to the horizontal. Its foot is pulled away from the wall through a distance 'a' so that it slides a distance 'b' down the wall making an angle beta with the horizontal. Show that: a=b tan(1/2(α+β)) .

A ladder rests against a vertical wall at angle alpha to the horizontal . If is foot is pulled away from the wall through a distance 'a' so that it slides a distance 'b' down the wall making the angle beta with the horizontal , then a =

A ladder rests against a vertical wall at an angle alpha to the horizontal. If the foot is pulled away through a distance 2m, then it slides a distance 5 m down the wall, finally making an angle beta with the horizontal. The value of tan((alpha+beta)/(2)) is equal to

A ladder leaning against a wall makes an angle of 60° with the horizontal. If the foot of the ladder is 2.5 m away from the wall, find the length of the ladder.

A ladder rests against a vertical wall at inclination alpha to the horizontal. Its foot is pulled away from the wall through a distance p so that it's upper end slides q down the wall and then ladder make an angle beta to the horizontal show that p/q = ( cos beta - cos alpha)/(sin alpha - sin beta) .

A ladder rests against a vertical wall at inclination alpha to the horizontal. Its foot is pulled away from the wall through a distance p so that it's upper end slides q down the wall and then ladder make an angle beta to the horizontal show that p/q = ( cos beta - cos alpha)/(sin alpha - sin beta) .

A ladder 3.7 m long is placed against a wall in such a way that the foot of the ladder is 1.2 m away from the wall. Find the height of the wall to which the ladder reaches.

A ladder 5 m long leans against a vertical wall. The bottom of the ladder is 3m from the wall. If the bottom of the ladder is pulled 1 m farther from the wall, how much does the top of the ladder slide down the wall

The angle of elevation of a ladder leaning against a wall is 60^@ and the foot of the ladder is 9.5m away from the wall. Find the length of the ladder.
