A 5-meter ladder is sliding down a vertical wall so the distance between the bottom of the ladder and the wall is increasing at 6 meters per minute.
Int

At a certain instant, the top of the ladder is 3 meters from the ground.
What is the rate of change of the area formed by the ladder at that instant (in square meters per minute)?

help please?

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

i believe that the answer is

b. y-1=-2(x-4)

hope this !

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
