A ladder of length x meter is leaning against a wall making angle `theta ` with the ground. Which trigonometric ratio would you like to consider to find the height of the point on the wall at which the ladder is touching
You are observing top of your school building at an angle of elevation a from a point which is at d meter distance from foot of the building Which trigonometric ratio would you like to consider to find the height of the building?
A ladder 5 cm long is leaning against a wall. The bottom of the ladder is pulled along the ground, away from the wall, at the rate of 2cm/s. How fast is its height on the wall decreasing when the foot of the ladder is 4 cm away from the wall ?
A ladder 16 cm long is leaning against a wall. The bottom of the ladder is pulled along the ground, away from the wall, at the rate of 2 cm/sec. How fast is its height on the wall decreasing when the foot of the ladder is 4 cm away from the wall?
A ladder is placed against a wall which is inclined at an angle 60^@ with the ground. The foot of the ladder is 4.6m. Away from the wall. Then the length of the ladder is
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 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 is situated against a wall in such a way that its foot is at a distance of 2.5m away from the wall and its vertex touches a window which is at a height of 6m from the ground.Then the length of the ladder will be
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.
