The foot of a ladder is placed 18 feet from a wall. If the top of the ladder rests 24 feet up on the wall, find the length of the ladder.
26 feet
27 feet
29 feet
O 30 feet

30 feet

Step-by-step explanation:

The ladder laying against the wall will create a right triangle.

The side lengths will be 18 and 24 and you will solve for the hypoteneuse which will be the length of the latter.

You can use the pythagorean theorm so

so you plug in the values

-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

might be the correct answer will be question number 2
