Answer:

<em>The ladder needs to be placed at 5 m from the wall.</em>

Step-by-step explanation:

<u>Pythagoras's Theorem</u>

Being a and b the legs of a right triangle and c its hypotenuse, then

$c^2=a^2+b^2$

The image shows a ladder of length c=13 m as the hypotenuse of the right triangle formed by the height, the ladder, and the ground.

We are given the height up the wall as a=12 m.

We calculate the distance b solving it from the equation above:

$b^2=c^2-a^2$

Substituting:

$b^2=13^2-12^2$

Operating:

$b^2=169-144$

$b^2=25$

Taking the square root:

$b=\sqrt{25}$

b = 5 m

The ladder needs to be placed at 5 m from the wall.

The percent increase from 18 to 26 is about...?

Shalnov [3]

Answer:

≈44.44%

Step-by-step explanation:

≈44.44%

To solve this, we can use a simple proportion.

Assuming 18 = 100%...

$\frac{18}{100}=\frac{26}{x}$

Then, using cross multiplication...

$18x=100(26)$

$18x=2600$

Now divide 18 from both sides.

x ≈ 144.44

Now subtract 100 from ≈144.44, leaving us with

≈44.44%
