How fast is its height on the wall decreasing when the foot of the ladder is 4 m away from the wall ?
A 10 Ft Ladder Is Leaning Against A Wall. Transcribed image text from this question. Dx/d(theta) when theta equals 60 degrees = 10cos(60).

Denoting the distance in feet between the wall and the base of the ladder by #x# and the angle in radians between the ladder and the ground by #y# #y = arccos(x/10)#. Find the height of the ladder in the first instance then subtract 3 from that answer and recalculate the floor distance using that new height remembering that the hypotenuse is fixed at 10. A ladder leaning against a wall makes a angle with the ground.
Length of the ladder = 10 foot.
If the bottom of the ladder is pushed toward the wall, find the rate at which x changes with respect to theta when theta equals 60 degrees. If the bottom of the ladder is pushed toward the wall, find the rate at which x changes with respect to theta when theta equals 60 degrees. A ladder leans up against a wall. A ladder leaning against a wall makes a angle with the ground.
