Answer:

$\huge\boxed{7.79 \ \text{feet}}$

Step-by-step explanation:

We know that we have a 9 foot long ladder resting upon a wall, with an unknown height, but the ladder is 4.5 feet away from the wall.

This can be represented as a triangle, where x is the unknown side.

x | \ 9

| \

|_____\

4.5

We can use The Pythagorean Theorem to find the value of x. The theorem states that $a^2+b^2=c^2$ , where a and b are the lengths of the legs and c is the length of the hypotenuse.

However, we already know the hypotenuse and one leg. Therefore we can substitute inside the equation to find the missing value.

$a^2 + 4.5^2 = 9^2\\\\a^2 + 20.25 = 81\\\\a^2 = 60.75\\\\a \approx 7.79$

Hope this helped!

Answer:

<3=48

Step-by-step explanation:

We know that <2 is also 132

Since a line is 180, we can do 180-132=48

That means <1 and <3 are 48

To check we can add them all together and get 360

I think this is right. The answer is 12.

24 times 9 equals 216, which is the area of the room floor.

Then I did 6 times 3 equals 18.

Then I divided 216 by 18 to get 12.
