Answer:

AC Midpoint (2,0)-

CB Midpoint (5,-4)

midlength is 5

Step-by-step explanation:

midpoint formula (\frac{x_{1}+x_{2}  }{2} ,\frac{y_{1} +y_{2} }{2})

A(2,4) C(2,-4)

\frac{2+2}{2} =\frac{4}{2}=2\\\frac{4-4}{2}  =\frac{0}{2} =0

(2,0)

C(2,-4) B(8,-4)

\frac{8+2}{2} =\frac{10}{2} =5

\frac{-4-4}{2} =\frac{-8}{2} =-4  midpoint is  (5,-4)

Distance between the 2 midpoints is the midsegment

(2,0) and (5,-4)

d=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})  ^{2}   }

d=\sqrt{(5-2)^{2} +(-4-0)^{2}  } \\d=\sqrt{3^{2} +(-4^{2})\\ } \\d=\sqrt{x} 9+16\\d=\sqrt{25} \\d=5

Help asap! will award brainly and pls explain!
cluponka [151]

This is a right angle triangle.

So, by Pythagoras theorem,

√(32^2+20^2) = x

or √(1024+400) = x

or √1424 = x

or <em>37.74 = x</em>

Can y’all plz help me ignore the writing part on the side of it plz show me the steps or tell me
Fiesta28 [93]
Hello.

The Manager has concluded that 2 out of 25 light bulbs are faulty.The table he created represents the ratio of bulbs checked and which ones were found faulty.
A way that he could verify that the table is correct is by simplifying each ratio. If each of them turn out to 2:25, then the conclusion is correct.

The best answer that matches this is answer choice "C.)" as it also defines our method of verifying the table's validity (just the order of the ratio is reversed, and that's fine as long as the variables are matching as well). We can further prove that this answer is correct by making ratios of our table and simplifying them;
100:8; divide both sides by 4.
25:2
500:40; divide both sides by 20.
25:2
2,000:160; divide both sides by 80.
25:2
This ratio is always the simplified answer.

Your answer is: "C.)"

I hope this helps!

How can you find the area of a polygon that is not for which you know an area formula
kipiarov [429]

Answer:

See below.

Step-by-step explanation:

If it is a regular polygon then you can look up the formula or break it into shapes you do know the formula.

If it is irregular or a composite figure, break it into regular polygons which do have formulas to find the area. Here is an example:

Example:

Find the area of the composite figure by splitting the figure into two shapes - two rectangles.

One rectangle is 2 x 9 = 18.

The other rectangle is 2 x 4 = 8.

Together the area is 18 + 8 = 26.
