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 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 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 slides a distance y down the wall making an angle beta with the horizontal.The correct relation is (A) x=y tan(alpha+beta)/(2) (B) y=x tan(alpha+beta)/(2) (C) x=y tan(alpha+beta) (D) y=x tan(alpha+beta) (in)

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 slides a distance y down the wall making an angle beta with the horizontal.The correct relation is (A) x=y tan(alpha+beta)/(2) (B) y=x tan(Q+beta)/(2) (c) x=y tan(alpha+beta) (0) y=x tan(alpha+beta) (a)

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 ‘a’ so that it slides a distance ‘b’ down the wall making an angle beta with the horizontal then the value of (a)/(b) is

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 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(alpha + beta) .
