Answer:

<h2>About 3.1 feet</h2>

Step-by-step explanation:

To find the missing lengths of a triangle, we must use pythagorean theorem. I'll put each part in steps so you can easily follow.

<h3>Step 1: Set Up the Equation</h3>

a^{2} + b^{2} = c^{2}

Note: c is the longest side of the triangle, the hypotenuse and a and b are the other two sides.

<h3>Step 2: Fill in Given Values</h3>

1.4^{2} + b^{2} = 2.1^{2}

<h3>Step 3: Multiply</h3>

1.96 + b^{2} = 4.41

<h3>Step 4: Subtract</h3>

1.96 + b^{2} = 4.41\\b^{2} = 2.45

<h3>Step 5: Unsquare b</h3>

b = \sqrt{2.45} \\b = 1.56524758424...

b = about 1.6

<h3>Step 6: Find the Chord</h3>

x = 2y = 2 * 1.57 = 3.14

about 3.1 feet

<h3>Step 7: Check</h3>

1.96 + 2.45 = 4.41

4.41 = 4.41 ✔

<h3>Step 8: Answer</h3>

x = about 3.1 feet

I'm always happy to help :)

Answer:

Step-by-step explanation:

Pythagorean theorem ,

y² = 2.1² - 1.4²

= 4.41 - 1.96

= 2.45

y =√2.45

y = 1.57 ft

x = 2y = 2 * 1.57 = 3.14

= 3.1 feet

The perimeter of a rectangular building is 1200 feet. The width of the building is 2 feet less than three times the length. What
juin [17]

Given:

The perimeter of a rectangular building is 1200 feet.

The width of the building is 2 feet less than three times the length.

To find:

Width of the building.

Solution:

Let length of the building be x.

Then, width = 3x-2

We know that,

Perimeter=2(length +width)

1200=2(x+3x-2)

1200=2(4x-2)

1200=8x-4

Add 4 on both sides

1204=8x

Divide both sides by 8.

\dfrac{1204}{8}=x

150.5=x

Now,

Width=3x-2

Width=3(150.5)-2

Width=451.5-2

Width=449.5

Therefore, the  width of the building is 449.5 feet.

Please help me with math please, they are number lines
Brums [2.3K]
So u have to rearrange to find x.
First u multiply by - 2 to get rid of the fraction bit
This leaves u with - 46>/x-49
Now u have to get x on its own which means you have to get rid of - 49 and to do this the opposite of - 49 is +49, so you would ADD 49
This gives you 3>/x

And the number line which represents this is B.
