Answer: 20 feet.
Step-by-step explanation:
Observe the right triangle attached.
You need to find the value of "x".
Then, you can use the Pythagorean Theorem:
Where "a" is the hypotenuse of the triangle, and "b" and "c" are the legs.
In this case, you can identify that:
Substitute these values into :
Now, you need to solve for x to find how far up the wall the top of the ladder reaches. Then you get:
Answer:
<h2>x < - 2</h2>
Step-by-step explanation:
First subtract 7x from both sides of the inequality
That's
<u>Add 10 to both sides of the inequality</u>
<u>Divide both sides by - 15</u>
Since the denominator is negative the sign will change
We have the final answer as
<h3>x < - 2</h3>
Hope this helps you

A Complex Number is a combination of a
Real Number and an Imaginary Number
and
Imaginary numbers, also called complex numbers, are used in real-life applications, such as electricity, as well as quadratic equations. In quadratic planes, imaginary numbers show up in equations that don’t touch the x axis. Imaginary numbers become particularly useful in advanced calculus.
