Answer:

Step-by-step explanation:

Pythagorean theorem will be applied to right triangles. The formula is a^2+b^2=c^2 where a and b represent the legs of the truss de c is the hypotenuse. Now let’s say I had a leg that was 4 inches and a second leg that was 8 inches. I would then have to try and find the hypotenuse. So plug it into the equation

4^2+8^2=c^2

Now 4 to the power of 2 is 16 and 8 is 64

16+64=c (note we got ride of the ^2 for the c)

So 80=c

Now what we want to do is take the square root of 80 since our c needs to be rooted. So the square root of 80 would be your answer.

Hope this helps

The area of a square is 144cm2.what is the measurement of each side

Dmitry [639]

The area of a square is 144 cm^2. The measurement of each side is 12 cm

<u>Solution:</u>

Given, The area of a square is 144 $cm^2$

We have to find that what is the measurement of each side.

Now, we know that, area of a square = product of side value with another side value.

Let the side value of given square be "s"

Then, <em>Area of square is given as:</em>

$\begin{array}{l}{\text {area of square}=s \times s} \\\\ {\text {Area of square}=s^{2}} \\\\ {144=s^{2}} \\\\ {s=\sqrt{144}} \\\\ {s=\sqrt{12^{2}}}\end{array}$

On cancelling square root and square on right side,we get

s = 12

Hence, the side value of the square is 12 cm.

which of the following gives an equation of a line that passes through the point (6 over 5, -19 over 5) and is parallel to the l

victus00 [196]

One equation for this would be

$y = \frac{41}{16} x-\frac{55}{8}$

We start by finding the slope between the two points:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{-12-\frac{-19}{5}}{-2-\frac{6}{5}}
\\
\\=(-12+\frac{19}{5}) \div (-2-\frac{6}{5})
\\
\\=(\frac{-60}{5}+\frac{19}{5}) \div (\frac{-10}{5}-\frac{6}{5})
\\
\\=\frac{-41}{5} \div \frac{-16}{5}=\frac{-41}{5} \times \frac{-5}{16}=\frac{41}{16}$

A line parallel to this one will have the same slope. We will use point-slope form to write our equation:

$y-y_1=m(x-x_1)
\\
\\y-\frac{-19}{5}=\frac{41}{16}(x-\frac{6}{5})
\\
\\y+\frac{19}{5}=\frac{41}{16}x- \frac{41}{16} \times \frac{6}{5}
\\
\\y+\frac{19}{5}=\frac{41}{16}x-\frac{246}{80}
\\
\\y+\frac{304}{80}=\frac{41}{16}x-\frac{246}{80}
\\
\\y=\frac{41}{16}x-\frac{246}{80}-\frac{304}{80}
\\
\\y=\frac{41}{16}x-\frac{550}{80}
\\
\\y=\frac{41}{16}x-\frac{55}{8}$

Please help me I think the answer is 12 cm .

-Dominant- [34]

You can find the value of the hypotenuse if you apply the Pythagorean Theorem, which is show below:

h²=a²+ b² ⇒ h=√(a² + b²)

h: hypotenuse (the opposite side of the right angle and the longest side of the triangle).

a and b: legs (the sides that form the right angle).

Then, you have:

h²=a² + b²

h²=12²+12²

h=√ ((12)² + (12)²)

h=12√2

What is the lenght of the hypotenuse?

The answer is: The length of the hypotenuse is 12√2
