Grandma and grandpa are painting gutters of their house. Grand leans a 12 foot ladder against the house which reaches 9 ft up the side of the house. How far away from the house is the base of the ladder? Please help my last

feet away from the house.

Step-by-step explanation:

This problem may seem a bit confusing, but after analyzing it closely we can see that Grand leaning on a ladder against the house forms a triangle, in which they want to know one of the legs.

Assuming that it is a right triangle, we can apply the Pythagorean Theorem:

Since the ladder is leaning against the house, and the houses side is our right angle, the ladder's height is our hypotenuse.

Therefore, we must reverse, or do the inverse of our formula:

Thusly, the base is

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
