11. Practice similar (1 point) A ladder 10 ft long rests against a vertical wall. If the bottom of the ladder slides away from the wall at a speed of 2 ft/s, how fast is the angle between the top of the ladder and the wall changing when the angle is w/4 rad? 10 rad/s7. Try again Practice similar Your answer is incorrect. The altitude (i.e., height) of a triangle is increasing at a rate of 2.5 cm/minute while the area of the triangle is increasing at a rate of 4.5 square cm/minute. At what rate is the base of the triangle changing when the altitude is 10.5 centimeters and the area is 94 square centimeters? The base is changing at 13.64 cm/min
